Description PJFSr 2011-09-24 20:23:06 UTC 
I'm running a duo boot windows (rarely used) and linux Ubuntu 10.04LTS when I try Pan .135 the screen turns gray for a long time when down loading headers, or if I click the search box and the CPU usage is 94-100%, also on large groups 150,000 it will just close the program. 

I have a stock gateway SX2801-o1e with 6 gigs of ram, 1TB HD partitioned 50/50 windows and Ubuntu.

I also have Pan .135 on my 9" ASUS eeepc900 wit 2 gigs of ram and 32gig ssd drive
running Ubuntu 10.04 with NO issues.

PJFSr.

Sample backtrace during search

It looks like searching triggers some crazy recursive calls within Gtk+, see backtrace.

Comment 5 Heinrich Müller 2011-11-28 11:40:26 UTC 
Took a look at it. Thansk for this useful patch. Works as advertised ;)
Merged into my branch.
Jindrich, did you create a diff from the official gnome repository?
Comment 6 Heinrich Müller 2011-11-28 11:41:01 UTC 
Btw, the close/open is still slow due to pan's handling of the articles.
