Current SVN ? 
I had believed this is fixed.

I still believe it was a fix, but maybe not for all possible reasons for the crash.
At least there were no more error reports until now, so it was not so bad.

Since we don't have a fix, 10352 should work around this class of crash bugs.
I'm pretty sure it's not the PendingBlocks getting corrupted, but rather the whole client got deleted.
But since you got as far as you did the deleted object's memory is still there and the workaround should work.

Ok, I've just compiled the latest sources and I am testing. It is not a frequent crash, only got it once, so this will be hard to reproduce.

BTW, are we already linking against wx 2.9.1?

Cheers!

[Stu Redman]

wx 2.9 support is there, but experimental.
2.9.1 works only in Windows, Linux needs wx SVN.

[phoenix]

Ok, thanks!
