qgis 1.6 crash if want save project

[bo27up]

Hello,

if I open and want to save the qgis crashes and the project file is damaged. This are the three last crash-protokolls:

please attach/link a sample of data (project+data) to try replicate locally.

Thank you for fast reply!

I'm working with Grass Plugin on QGIS. Here are the steps which leads to a crash.

1. Load a Polygon (Grass-)Data

2. Load Raster (Grass-)Data

3. Try to save Project => Crash, Project Data is damaged

4. Open Project again (project data was saved on another place before)

5. Close Raster Data, then try to save => it works!

6. Close Project and restart Project (only Polygon Data is loaded as saved before)

7. Try to save => it works!

8. Then open Raster Data again and try to save (Polygon and Raster) => it works!

9. Close Project and restart Project again

10. Try to save => Crash, Project Data is damaged.

11. If I repeat step 4. until 10. I get the same behavior as decribes.

So QGIS crashes if Polygon and Raster Data is loaded, but only after second save-process. In the first time when its loaded (Polygon and Raster), its no problem with saving. After restart the Project the save-process crashes every time. If there is only Polygon Data loaded, there is no problem.

It's not possible for me to attach Data because there is a limit of 256kb. I will try to generate smaller sample data.

I'm using qgis trunk on ubuntu 10.04 32 bit.

1. Load a Polygon (Grass-)Data

2. Load Raster (Grass-)Data

3. Try to save Project => Crash, Project Data is damaged

not replicable here.

4. Open Project again (project data was saved on another place before)

5. Close Raster Data, then try to save => it works!

6. Close Project and restart Project (only Polygon Data is loaded as saved before)

7. Try to save => it works!

no problem here also

8. Then open Raster Data again and try to save (Polygon and Raster) => it works!

no problem here also

9. Close Project and restart Project again

10. Try to save => Crash, Project Data is damaged.

not replicable here.

It's not possible for me to attach Data because there is a limit of 256kb.

link it instead of attaching it.

Grass-Data

[bo27up]

I attached the Data. Every time when I start the Project by double clicking the Project-file and then directly try to save the Project it crashes.

Remarkable is, that I get sometimes an error in libgcc_s.so.1 and sometimes in libc-2.11.1.so , by doing everytime the same (Open Project-file -> try to save Project => crash!)

The attached data works fine with trunk and ubuntu 32 bit. Please try qgis trunk and report back.

Ok, I tried it with Trunk and 1.6 on a Virtual Machine (Ubuntu 10.04 - 64bit) and both works fine. Any Idea what I could try to fix the crashes on my machine? Maybe uninstall and install qgis 1.6 ?

Replying to bo27up:

Maybe uninstall and install qgis 1.6 ?

should be easy to test.

Meanwhile I'll close this ticket. Reopen it if you find a way to replicate the problem.

[bo27up]

I found the "evildoer". It's a Python Plugin calls "SDA4PP".

My last Crash-Protokol was this here:

Apr 25 21:41:50 jojo kernel: [  540.742948] qgis.bin[1978]: segfault at 0 ip 00007fb5f16ce87b sp 00007fff55a1a220 error 4 in libR.so[7fb5f15fe000+2bb000]

So I guess first it's the Plugin "manageR", but after I'd uninstall Plugin's which use the R librarys I find out that SDA4PP is the Problem! Without this Plugin it works fine.

[lutra]

SDA4PP is a 3rd party plugin, so the issue has to be filed directly to the author. In a few days/weeks will be published also the bug tracker for plugins, so if no feedback is given will be also possible to file a ticket there.
