GRASS 6.4.0svn (nowa_lokacja):~ > 
(python:26751): Pango-CRITICAL **: pango_layout_get_cursor_pos: assertion `index >= 0 && index <= layout->length' failed

6.4 branch r37101, Debian stable amd64, python 2.5.2, wx 2.8.7.

Unable to reproduce it. Undocking works.

6.4 branch, r41467, Debian unstable 32bit, python 2.5.5, wx 2.8.10.1 (gtk2-unicode)

Please try to upgrade your wx libs.

Docking an undocking works just fine when there are NO maps displayed.

Steps to reproduce:

• add raster or vector map;
• undock map display toolbar;
• dock back map display toolbar --> KaBOOM!

just another data point:

I can reproduce this in 6.4 and 6.5, but I have to try for a minute or two first (it's on a rather fast machine, which may help, although I am running X tunneled over ssh from it). I got no error message when the wxGUI was launched automatically at startup.

I notice that draging the toolbar is not the most responsive thing once a map is loaded. I had to try harder in 6.5, but that might just be chance.

Running same Debian/stable (lenny) amd64 with python-wxgtk2.8 version 2.8.7.1-1.1+lenny1 and python 2.5.2-3.

Also I notice that if I remove or uncheck everything on the list the last map standing does not clear from the display window. If I press the erase button, the image comes back after I tear-away or reconnect the display toolbar.

I suspect that this is an upstream bug, and there is little we can do about it.. but no idea.

wow, I just restarted grass in text mode and then g.gui from the command prompt, and it died after adding a raster map and then a vector map with:

(hamish:10965): Pango-CRITICAL **: pango_break: assertion `attrs != NULL' failed
(hamish:10965): Pango-WARNING **: shaping failure, expect ugly output. shape-engine='BasicEngineFc', font='Bitstream Vera Sans 9.9990234375', text=''

maybe I should try restarting X now..

Still relevant with recent SVN version?

Replying to martinl:

No more crashes in current 6.4.svn and 7.svn.

Closing since it appears to be fixed. Reopen if needed.
