[Pkg-cairo-dock-devel] Bug#690811: cairo-dock: segfault at startup after several failed assertions

[Yann Dirson]

Package: cairo-dock-core
Version: 3.0.0-2
Severity: important

Running under openbox, launching cairo-dock to get a look at it just
causes a segfault.  Nuking .config/cairo-dock and requesting it to
disable OpenGL does not help.

May be related to those failed assertions it shows first ?

Gdb can't say much with a -dbg package to help, here is what I get:

$ gdb cairo-dock
