 Trunk r9205, QT 4.4.0, Debian testing amd64.

 1. load a bitmap in georeferencer

 2. add 4 GCPs at corners

 3. pres "Create" ("Linear" transformation)

 4. you realise point coordinates are bogus

 5. try to delete all points - one of them will resist (at least for me);
 QGIS also sometimes deletes another point instead of the one you click

 Sometimes deleting the points or if "Create and load" is done instead QGIS
 crashes:
