Code: Select all

Application: KTorrent (ktorrent), signal SIGABRT

Do you happen to know what got printed on the command line ?

Nope, normally i do not load it from the command line.

Upgrade to rev 914495.

As of now all fatal Qt messages will end up in the log, so the next time this happens, the last line in the log should be what we need, to debug this problem.
