Comment 12 for bug 582838

I have just updated from bazaar 2.2.4 and bzr-explorer 1.1.0 to bazaar 2.4.1 and bazaar explorer 1.2.1. (Ubuntu maverick using bzr ppa)
I have a tree with about 12k files, and I had no problems prior the update but since the update, after opening my tree, bzr explorer hangs some minutes and takes 100% of one core.
I have started bzr explorer via the command line, and when it begins eating 100% cpu, the console permanently outputs the following line (about 5-10 lines / second)

root: /mnt/storage/var/www/fcp/main
root: /mnt/storage/var/www/fcp/main
root: /mnt/storage/var/www/fcp/main
...

I think this problem is similar/related to this bug here, though I am not sure.
I think with this less info you won`t be able to find out what the problem is, so can someone give me some hints on how to get more infos about what bzr is actually doing when consuming 100% cpu?
