Firefox freezes entire desktop interface when moving 200 bookmarks to Unsorted Bookmarks

[komputes]

Binary package hint: firefox-3.5

Firefox freezes entire desktop interface when moving 200 bookmarks to "Unsorted Bookmarks". The cursor is the only thing which is responsive. To escape from this bug I must move to a VT and force firefox to quit.

Steps to reproduce:
1) Create new profile
2) Import bookmarks (Large File - 1MB)
3) Move 200 Bookmarks to Unsorted Bookmarks

Result:
Firefox freezes entire computer interface

Expected result:
200 Bookmarks are moved to Unsorted Bookmarks

Current workarrounds:
a) ctrl-alt-f1, log in, killall firefox, ctrl-alt-f7
b) move bookmarks in batches with fingers crossed
