[DebianGIS-dev] Bug#606304: qgis crashes when I resize the window

Wed Dec 8 09:04:59 UTC 2010

Package: qgis
Version: 1.4.0+12730-3+b2
Severity: important

When I load a shapefile, and resize qgis to full-screen and back
(using ion3's full-screen hotkey), qgis crashes (backtrace below,
valgrind log attached).  That does not happen when the map is empty.

libqtcore4/libqtgui4 4:4.6.3-4 is installed.

Program received signal SIGSEGV, Segmentation fault.

==15092==  If you believe this happened as a result of a stack
==15092==  overflow in your program's main thread (unlikely but
==15092==  possible), you can try to increase the size of the
==15092==  main thread stack using the --main-stacksize= flag.
==15092==  The main thread stack size used in this run was 8388608.
