QGIS crashes

[camerons]

Open QGIS (from command line if you want to see error logs) Follow first 2 quickstart steps:

1. Launch QGIS from Geospatial ‣ Desktop GIS ‣ QGIS and select Project ‣ Open from the menu bar.

Open a QGIS project

2. Choose QGIS-NaturalEarth-Example.qgs and press Open.

QGIS crashed. (I assume it ran out of memory). Tried again but opening the other example dataset: Itisca, and the datset did open without crashing.

I was running using VirtualBox on a Mac, with 1024 Gig RAM allocated, booting from an ISO.

This issue also crashes QGIS server demo

The project file is from an older QGIS version and it takes a long time to open.

[kalxas]

Since we upgraded from 2.14.3 to 2.14.11, there should not be a project file incompatibility. I think this is a bug or something gone wrong in a backport...

We definitely cannot release 10.5 with this one...

[kalxas]

It looks like we have a deeper problem to deal with. Beta1 included the same QGIS package as RC1 but RC1 crashes on the Natural Earth project file, while everything works fine in beta1...

[kalxas]

I have generated new qgs files:

​http://aiolos.survey.ntua.gr/gisvm/dev/QGIS-Itasca-Example.qgs ​http://aiolos.survey.ntua.gr/gisvm/dev/QGIS-NaturalEarth-Example.qgs

RC1 crashes with the new files too.

I reverted QGIS to 2.14.10 and built a nightly for testing, same issue.

I think this crash has to do with some other update we got from upstream.

[kalxas]

Bingo!

Got 10.5beta1 iso running on a vm, did an apt-get upgrade, issue now appears on this system too.

Some recent Ubuntu update is the culprit...

[kalxas]

And the culprit is...

​http://packages.ubuntu.com/xenial/libtiff5

Starting from 10.5beta1 iso, do the following to reproduce:

• Try QGIS, everything works

• sudo apt-get install libtiff5 libtiff5-dev libtiffxx5

• Try QGIS, NaturalEarth project broken.

Now this one is a security update, so the proper fix would be for us to include this package in our ppa and re-build everything on top of it...

Fix committed:

[kalxas]

With the latest commits, I was able to get QGIS back to working, but as a side effect, rasdaman installer now fails (we are not able to change this installer, since it is not in our git repository).

[kalxas]

After looking deeper, I realized we need to make a full transition for libtiff5 (also needed for UbuntuGIS ppa)

[rouault]

I'm not sure if this is related but it is known that Debian applied a wrong version of an upstream libtiff security fix: ​http://www.asmail.be/msg0055438562.html But this issue shouldn't cause a crash.

[kalxas]

Thanks for the feedback Even.

I completed the transition last night and I have a new iso:

​http://aiolos.survey.ntua.gr/gisvm/dev/osgeo-live-nightly-build78-amd64-e169950.iso

Unfortunately the issue was not fixed.

I am 100% sure this is a libtiff issue (see comment 8 above), but I am not sure why it causes this crash (actually the crash happens only with the natural earth QGIS project, which directly opens a tiff file)

[kalxas]

Some progress finally: since patching libtiff5 did not work as expected, I have created a patch that reverts the Ubuntu update. After testing this patch on top of RC1, we have a working QGIS again.

I am building a new nightly iso to confirm the fix and will update this ticket.

[kalxas]

Confirmed fixed in nightly 79.

The new tiff package is available both in nightly and release ppa, and follows the ubuntu naming conventions, so that it will be overwritten by a new ubuntu security update.
