[Launchpad Bug Tracker <754009@xxxxxxxxxxxxxxxxxx>]

You have been subscribed to a public bug:

1)
System: Linux Mint 10(Julia) Gnome 64bit

Hardware: Core 2 Quad, ATI HD 4870
Software: 
- fglrx 2:8.780-0ubuntu2
- xserver-xorg 1:7.5+6ubuntu3
- kdevelop 4:4.0.2-0ubuntu2


2)
- start kdevelop
- create a C++ project 
- right click on the project in the project area to the left and select "Create Class"
  A wizard pops up, guiding the user through the process. At the end the wizard tries to open  a window in which 
  the new class gets included into the CMakeLists.txt file - at this moment the Xserver crashes.

3)
The Xserver crashes, the session is lost, gdm is starting the Xserver again to show the login prompt.

In /var/log/gdm/:0.log.1 the glesx.so module of fglrx shows up in the
backtrace:

...

Segmentation fault at address 0x18

Caught signal 11 (Segmentation fault). Server aborting

...

4)
Well, no crash. ;)
When using the open source driver instead no crash happens. Together with the backtrace it makes me believe 
that the fglrx part is involved.

5)
The crash happens always.
