There are two issues here:

1. The application somehow issued an X error, most probably when 
trying to get X window properties of an already closed window. Might 
be an issue in KDE, see multiple backtraces containing 
NETWinInfo::update[1] or XGetWindowProperty[2]

2. GDK installs a deadly X error handler, causing the application to 
exit, instead of "just" printing an error message. See multiple 
backtraces containing gdk_x_error[3]

Even if the first issue got fixed, I consider the second issue rather 
critical, and suggest to not call a previously installed X error 
handler. Comments?
