Description Simon McVittie 2008-02-29 07:55:29 UTC

Alberto Mardegan reports a crash in Mission Control that is only reproducible under Valgrind, which appears to boil down to:

15:46 < smcv> so you make a call
15:47 < smcv> you unref the channel
15:47 < smcv> the channel is kept alive by the call
15:47 < Mardy> yes
15:47 < smcv> you now dispose of the weak_object for that call
15:47 < smcv> and it crashes?

I suspect this may be telepathy-glib's fault.

Comment 1 Simon McVittie 2008-02-29 08:22:42 UTC

It turns out that the problem is caused by:
* make a proxy, p, and an object, o, each with one ref
* make a function call with o as weak object
* connect to a signal with o as weak object
* unref p
* unref o

Fixed in 0.7.4.
