After upgrade to Natty Gmusicbrowser crash many times a day.
I'm using Ubuntu 64 and the Andreas' ppa.
Normally occurs in the labeling process.
Searching info in Discogs with Web Context plugin and edit tags.
Runnig gmusicbrowser from terminal I get messages like this:

But in normal use It simply disappears without message.
Any idea to fix this people?  :(

My guess would be the flash plugin crashes the mozembed or webkit library, unfortunately, I don't know of a way to disable flash (apart from uninstalling it)

Thanks for answer.
So we have a guilty
I will try with Flash player "Square" Beta from Adobe site, fingers crossed.

i don't want to discourage you, but i've had really bad experiences with flash and mozembed, in fact it was one reason why i decided to leave it behind (and wrote the artistinfo plugin to get some info).

Sure, with Flash in general...
However, with the beta version doesn't crash so often (Only one time this afternoon) and the terminal messages have been reduced to :

Gdk-WARNING **: XID collision, trouble ahead at /usr/bin/gmusicbrowser line 1269.

After this warning the cursor outside the context web frame, but inside gmusicbrowser, is always the hand to point links...
Only changes its status correctly inside the context web frame.
Outside gmusicbrowser the cursor works normally.
Not a big deal but strange...
