fglrx makes chromium-browser segfault on exit (every time)

[jimav]

With fglrx installed, chromium-browser segfaults when exiting, every time. Even if nothing has been viewed: With home page set to "about:blank", start browser and immediately do menu->Exit

Here is a gdb trace (ran with /usr/bin/chromium-browser -g). Note that the stack appears to be over-run/corrupted:

Un-installing package fglrx makes the problem go away. So at first blush it seems like /usr/lib/fglrx/libGL.so.1 may be responsible.

I don't see how to change the package for this bug report to 'fglrx' ...

[Andreas Moog (ampelbein)]

You can click on the little arrow besides the package and choose a different one there. I now assigned this bug to the fglrx package.

Status changed to 'Confirmed' because the bug affects multiple users.
