Here's gdb backtrace:

#0  0xffffe410 in __kernel_vsyscall ()

It seems that libfbclient tries to acquire some lock that is still busy.
There are no other users on the server/database.

Manually disconnecting from database before closing the main window
seems to fix tre problem. Hopefully, this rings some bells...
