Description Charles Samuels 2014-05-20 22:35:19 UTC
When a plain Qt program detects a KDE session, it likes to use KFileDialog, KFileDialog then locks up and blocks the program indefinitely while trying to use samba. According to strace, KFileDialog runs /usr/bin/testparm which produces some output and then exits, and that's the last thing that makes any sense from strace.

I've seen this on debian stable, but it was reported to me from a Kubuntu 14.0 user. Removing the Kubuntu package samba-common-bin seems to workaround it. 



Reproducible: Always

Steps to Reproduce:
1. Make sure samba-common-bin and smbclient packages are installed on your machine
2. open a QFileDialog from a Qt application from inside a KDE session. I've seen this on BitcoinArmory, and I suspect it's reproducable on vlc as well.
3. The program should now be blocked.

Is this still reproducible in KDE Plasma 5, Qt5, KDE Frameworks 5.x, and a more recent version of libsmbclient?
