Steps to reproduce:

1. Open a terminal
2. cd to pwb core repository
3. Run git pull --all and git submodule update to be synced with current master
4. Login to pwb
5. Run python pwb.py cosmetic_changes -page:"Stefan Grot-Rowecki" on cswiki
6. Hit y to confirm cosmetic_changes running standalone

Expected result:
It should show changes made and confirmation text immediately.

Current behavior:
The bot freezes when editing some articles (on some articles for some minutes, on some other articles forever, like the one in the example)

Last week everything was ok.
