evolution crashed with SIGSEGV in pixbuf_set_transparency()

[Chris Halse Rogers]

Evolution crashed while running in the background. It's done this a couple of times before with the same backtrace, so it looks like there's a semi-reproducible problem here.

Possibly a problem in unico?

looks like evolution is sending NULL pixbuf pointers?

[Chris Halse Rogers (raof)]

What information would you like me to gather; what could change this
from Incomplete to something useful?

[Andrea Cimitan (cimi)]

Well, it's an issue in packaging:
unico was built with the nanoversion (0.1.0.1), the nanoversion is here just for development, an disables assertions (so an assertion similar to g_return_if_fail (pixbuf != NULL); ).
It will be immediately fixed when I'll do a stable release of unico, or once I'll do a snapshot with the assertion enabled on development mode.

[Pedro Villavicencio (pedro)]

If i understand correctly this was fixed already?
