I demand that Pasi Juppo may or may not have written...

According to man pages VDR uses by default the highest level of logging. I didn't change the level but still VDR did not put log anything when TVOnScreen plugin crashed (crashed because there was no EPG data on any channel and enter was pressed few times).

Did the plugin crash caused segfault to VDR thus no logging was possible or am I missing something?

Probably the best thing to do is to get it to dump core.
