Error messages differ, sometimes I get (as terminal output):
----

and evince quits.
Comment 1 Thomas de Grenier de Latour 2005-05-26 17:38:46 UTC 
I have troubles for reloading PS files too (with 0.3.1), but no crash. When I
hit the refresh button, it just hangs, and in console i can read:
*** glibc detected *** double free or corruption (fasttop): 0x082ed628 ***

I'm sorry, but I don't know how to get some backtrace when i don't have a core
file :-/
Any hint would be appreciated, so that i can report back something more useful. 
Thanks.
Comment 2 Nickolay V. Shmyrev 2005-05-27 00:15:26 UTC 
Yeah, the problem exists. I think we have problems with locks here but we should
investigate it.
Comment 3 Marco Pesenti Gritti 2005-05-31 14:39:36 UTC 
Now it works if you dont reload while it's still rendering...
Comment 4 Marco Pesenti Gritti 2005-05-31 16:14:12 UTC 
Ok the locks is a pretty bad issue.

Basically the old document is holding the doc mutex until rendering is finished,
the new document tries to get the lock -> hang

I guess the possible solutions are to wait rendering is done before loading a
new file or to make the lock per document rather than global.
This issue applies to all backends, ps expose it because it's slow to render.
Comment 5 Marco Pesenti Gritti 2005-05-31 16:28:33 UTC 
Well, actually the ps case is special because we render on the main. Will have
to talk about this with jrb.
Comment 6 Marco Pesenti Gritti 2005-06-07 09:22:05 UTC 
This should be fixed in cvs
