[Julietsl]

I was looking at bittorrent transmission remote GUI update in ubuntu software updates when this happened. It happened after I went to look at the website link in Ubuntu Software Center and then got back to the Software Center.

I didn't manage to reproduce that crash. I'll try with previous revisions of the code.

Does anyone manage to reproduce it?

Julietsl: Is it still crashing with the current versions?

[Julietsl (julietsl)]

Loic: I haven't tried to reinstall compiz again. Frankly I'm not too keen to
try it out again considering last time I had to reinstall Ubuntu all over
again. I had no idea how to fix the issue otherwise.

It seems like this bug is fixed now since nobody can reproduce it and there's no comment apart from the only duplicate that's been reported more than 1.5 months ago.

[David Barth (dbarth)]

Closing the bug. The bug can't be reproduced anymore, there are no testcases, besides there are no more reports of it happening.

[Julietsl (julietsl)]

Dear Loïc,

Thank you for resolving the issue. I will try installing it again then. And
will let you know how it goes.

Juliet.
