I was doing nothing... I can't reproduce it.
tindal

PS this is the right place to post backtraces, isn't it?
I posted 1 in the bug-tracker before reading this:
"However, please note that backtraces should only be posted if it is a reproducible bug, otherwise you should post the backtrace in the backtraces forum"
sorry

[phoenix]

tindal,

This is the right place for posting backtraces.

Thanks for reporting!

I don't see much what we can do about it, it is surely some memory corruption. We suspect it is related to the non-reentrancy of wx sockets. The case is under study.

Cheers!

[tindal]

here is another one
I can't understand anything in backtraces, but this one seems very similar to the other.
The question is: is it useful that I continue posting similar backtraces?
