My version is 2.0.2, the default one with fedora core 3. The issue imho is not with the stability of evolution as it can handle a couple of imap/pop mail boxes perfectly fine. The folder that I am trying to access is huge (around 55K mails and would be around atleast 10 - 20 MB in size). Evolution takes ages attempting to scan this folder, and finally when the cpu usage crawls to above 90 %, i do a killall evolution.
Which component is hanging would be a tough question. I could run it in gdb if you want, but then if the cpu usage climbs up I dont think i would be able to get a bt :(
BTW, is it possible to download only incrementally the new files or any other method to make the whole process faster ?
