As per title, avogadro-1.0.1 crashes with a segmentation fault on startup under KDE 4.6. In particular it segfaults during GLWidget initialization. The actual output I receive is the following: "Avogadro version: 1.0.1 Git: LibAvogadro version: 1.0.1 Git: " Locale: "en_US" Libavogadro translations not found. "System has OpenGL support." "About to test OpenGL capabilities." "OpenGL capabilities found: " "Double Buffering." "Direct Rendering." "Antialiasing."

Segmentation fault I believe the problem to be related to EGL. This is because with KDE 4.4 I was using GLX and avogadro was working just fine. Also, if I re-emerge it with USE="-glsl", it starts all right, but the drawing area is all messed up and unusable. The output above is for a 64 bit arch, but I tried it on a 32 bit machine and behavior and considerations are EXACTLY the same.
Please post your `emerge --info' output too.

If its still relevant to 1.0.3 please reopen
The bug is still present in version 1.0.3. The output of avogadro is: "Avogadro version: 1.0.3 Git: LibAvogadro version: 1.0.3 Git: " Locale: "en_US" Libavogadro translations not found.

Upon further investigation, the bug seems to be related to mesa. In fact, with mesa-7.11 the error is no longer present. However, avogadro still does not work, as it apparently triggers yet another mesa bug, this time related to _mesa_select_tex_object. The output follows: "Avogadro version: 1.0.3 Git: LibAvogadro version: 1.0.3 Git: " Locale: "en_US" Libavogadro translations not found. "System has OpenGL support."

Mesa 7.11 implementation error: bad target in _mesa_select_tex_object() Please report at bugs.freedesktop.org Segmentation fault This seems to be related to this very old bug in mesa: https://bugs.freedesktop.org/show_bug.cgi?id=24342 However, as the poster on freedesktop.org points out, this should not happen with correct core. Thus, I'm not marking this bug as invalid, but leaving it open.
lease try again with latest packages and reopen if still exists.
