it's much better now, but after adding and removing keywords on many mails 
I got an assert again:

Core was generated by `imap'.

I've seen another issue (maybe relatet to that bug). It seems that the 
virtual folder a just increasing. There are 4 KEYWORD Mails. I see all the 
mails in the virtual keyword folder. After the removal of the keywords 
form two mails, there are still 4 mails in the virtual folder, but two are 
shown without the keyword. I think the two mails should be removed from 
the virtual folder.

kind regards,

Matthias
