I set up a virtual search folder to find big messages (>1mb) through all my email accounts (4 imap, 1 local maildir). Then after some days I realized that kontact uses ~800mb memory. Deleting the search folder and restarting kontact solved the problem. But I think it shouldn't behave like this. Reproducible: Didn't try Steps to Reproduce: 1. Create a virtual folder for big emails 2. restart kontact 3. Actual Results: huge memory usage Expected Results: shouldn't be more than usual (~70mb in miy case)
kontact doesn't seem to support searches across imap accounts, so marking this one as "fixed" (kinda) ;-)
