-- Information about the crash:
Hi there! I just upgraded to KDE 6.2.1 two days or so. KDE 6.2.x seems to be the least stable release of KDE 6 so far ;-) With KDE 6.2.0 I had the issue that I wasn't able to login anymore after the monitor got black and the screen got locked after a while of inactivity. While I was able to type in the password, the screen didn't unlock no matter if I used the "enter" key on the keyboard or the ">" button right to the password field. I had to click "switch" user and then login again with the same user. That worked. Now with KDE 6.2.1 I had this crash. I was doing nothing special. Just was using Firefox and clicked on a link and then it crashed. Basically all my open windows were closed afterwards. I only got all my Konsole windows back (all at the same position in the same activity while they're normally distributed around three different activities). I had six different Firefox instances open (so not six windows but really six different Firefox profiles all on their own). I also got a crash report of all these Firefox instances. That's actually all the information I can provide. I hope this helps.

The reporter is unsure if this crash is reproducible.

Crash just happened 10-15 minutes later again. I have the feeling that this related to the Xpra (https://xpra.org) update. Xpra is very handy when working with multiple computers but only one screen. E.g. I'm starting Firefox on a remote machine via SSH + Xpra and the Firefox window appears as I'd have started Firefox locally. I upgraded from version 4.4.5. to 6.2.0 this morning. Xpra is always a bit special but I've never seen that it crashes that hard. Normally it just doesn't work e.g. if Xpra version doesn't match on local and remote host or if some video codes are not there. But that's it.

Looks like downgrading Xpra from 6.2.0 to 4.4.5 "solved" the issue. Haven't had the crash anymore so far. But without a fix I'm not really able to update Xpra anymore.
