I missed Klaus' email so I reply to this one.

Plugin crashes come from normal usage (vdr might have been running for 
quite some time) where plugin simply performs illegal operation. For 
instance I got crash from MP3 plugin when I tried to play accidentally 
.txt file in the same directory. Also, OSD PiP causes crash when I choose 
e.g. MTV3 (Finland, Vaasa) for PiP and start jumping channels forward till 
VDR changes mux (I presume, not sure) and PiP does not tolerate it.

Anyhow, these are more or less plugin related problems but is there any 
way to catch the exception in VDR and exit with error code? Or better yet, 
recover from the fault and start the plugin again (preferably error 
message to /var/log/messages about the happening).

One more thing. I don't think it is segmentation fault. VDR simply 
shutdowns itself (no error messages to log or to the shell).
