Package: libqtcore4
Version: 4:4.8.2+dfsg-11
Severity: important
Control: affects -1 hplip-gui
Dear Maintainer,
using `hp-systray` from the package `hplip-gui`, it segfaults in
`libqtcore4`.
hp-systray[2965]: segfault at 40 ip 00007f7a6c03e594 sp 00007fffb58e2068 error 4 in libQtCore.so.4.8.2[7f7a6beb0000+2c8000]
Strangely the problem only showed up lately. I am not sure if HP Systray
is used differently by the user or something else changed.
Fortunately a core dump file was written to disk, so GDB is showing the
following backtrace after installing the packages with debugging
symbols.
$ gdb python -c core
[…]

Hopefully you can think of a fix, which might even make it into Debian
Wheezy.
