Bug#646507: opening URL makes iceweasel consume about 100% of CPU time

[Andrew O. Shadura]

Package: iceweasel
Version: 9.0~a2+20111014042012-1
Severity: normal

Every time I open http://malovane-mapy.sk/ in a browser, it hangs. Doing
gdb attach did give me any meaningful trace information, unfortunately
:(
