After updating to Ubuntu 16.04 LTS I am geting a crash for bitlbee:

There are access tokens in your debug log. You might want to change your password to invalidate them.

The bug seems to be in bitlbee-facebook, not bitlbee.

Can you reproduce this every time?

Please install valgrind, kill the current bitlbee processes, and run

BITLBEE_DEBUG=1 valgrind --log-file=valgrind.log bitlbee -Dnv

Valgrind will probably prevent the crash and continue running, but write relevant debug output to valgrind.log. Please post that if it shows anything.

Don't worry about the tokens, I've modified them :) I've tried to uninstall, purge and then reinstall. Also renamed the config folder so that I can start a new account. As soon as I've issued a register 'password', bitlbee crashed.

Ok, found out something interesting. I've installed mirc client , instead of kiwi irc. And with this one, it won't crash. So it must be something with kiwi weblient, that causes bitlbee to crash.

[dx]

(added code block to description)

That's a very different crash. Upgrade to the latest git version to fix it. I hadn't seen that one in the wild until now, sucks that kiwiirc triggers it.

But I don't think it's relevant to the first one you posted.

Also, please build bitlbee with ./configure --debug=1

[dx]

Okay, going to assume this issue is actually ​bitlbee-facebook's ticket #82, given the timing of this report and others.

The kiwiirc issue, while unrelated to the original report, should be handled with this: ​https://github.com/prawnsalad/KiwiIRC/pull/876
