Comment 1 for bug 130300

strace from a running ktorrent where I activate uPnP plugin and quit from ktorrrent and get a crash.

was displayed kde crash handler with this message:

This backtrace appears to be of no use.
This is probably because your packages are built in a way which prevents creation of proper backtraces, or the stack frame was seriously corrupted in the crash.

Using host libthread_db library "/lib/tls/i686/cmov/libthread_db.so.1".

unable to create a valid backtrace.
