Bug#803284: plasmashell: Crash in xcb_send_request/xcb_intern_atom
Package: plasma-workspace
Version: 4:5.4.2-1
Severity: grave
File: /usr/bin/plasmashell
Justification: renders package unusable
Dear Maintainer,
After the latest KDE version bump (4:15.08.2-1), some critical KDE components,
including plasmashell, segfault on startup, making KDE almost completely
unusable.
The crash happens after calling xcb_intern_atom, and in some cases (konsole)
after calling XInternAtoms. A bug report against kate was filed by someone else
as #803212. A crash log (with some debug info) is attached.
At the same time as the KDE upgrade, I received some new xorg packages. It is
possible that this is not a bug in KDE at all.
