Seems as though I got my first dose of this while using kde4 this morning. My mail had 3 "No Subject-Unknown sender" emails in my inbox. Gmail caught and archived the emails before they were filtered. 1 email was actually an important email. I tried looking around at logs, and realized that I did not have filter logging turned on, so that is now active for future problems.
I found that kmail logs to ~/.xsession-errors, so I began to look around there. Something I found while tailing the file, is that is consitently writes out: kontact(5489)/kmail KMail::CachedImapJob::slotPutMessageInfoData: Server told us uid is: 5778 kontact(5489)/kmail KMail::CachedImapJob::slotPutMessageInfoData: Server told us uid is: 5779 kontact(5489)/kmail KMail::CachedImapJob::slotPutMessageInfoData: Server told us uid is: 5780 kontact(5489)/kmail KMail::CachedImapJob::slotPutMessageInfoData: Server told us uid is: 5781 With different uid's, incrementing by 1 each time. I am not sure if that is normal. I grepped around the log and nothing was mentioned of these lost emails.
