claws-mail crash during filtering

[girarde]

Lately, claws-mail has begun to crash while filtering messages in my primary account. According to the claws-mail -d output, it tries to start another instance of itself, and fails saying 'can't run more than one.'

The @misc, @ports, and the claws-mail user list are unresponsive. I filed a claws-mail bug, and was told "but it doesn't try to start itself".

Has anybody encountered this sort of thing? I've long had a problem with extended search in folders with lots of messages, but this is recent.

I switched to Sylpheed a few years ago, I can't exactly remember why. I think it was because Claws Mail was a bit too slow to deal with a high number of messages.
They are very similar and it's easy to switch.
You can replicate your configuration at least while you're facing this problem.

Thanks, I'll look into that if the problem recurs - I cleaned out some duplicate and antiquated filter rules and it's behaving better for the time being.
