Bah, should've at least tried to reproduce before answering. The backtrace I get (see \
below) could mean this is actually a Qt problem. I also get this output on the \
terminal: X Error: BadWindow (invalid Window parameter) 3
  Major opcode:  40
  Minor opcode:  0
  Resource id:  0x0

Program received signal SIGSEGV, Segmentation fault.

Here's the backtrace:
