Hi there,
we started to use x2go via ssh proxying.
From there on we experience segmentation faults. In the syslog excerpt below you can see that it starts with the segfault. The last line with the pulse audio is repeated hundreds of times.
Server: Kubuntu 12.10 amd64, version 4.0.1.13-0~814~ubuntu12.10.1
Client: Windows 7 Professional SP1 - 64bit, X2GoClient V. 4.0.1.3 (Qt - 4.8.5)
After the crash there is a stale session.
Any clue what reason it could be?
Cheers, Matt
