SUMMARY Since either since last update to Kmail (yesterday I pulled in the 5.15.5 update) or since moving an email into the folder, I am experiencing a consistent freeze of the Kontact application upon attempting to view the contents of an email folder. The Kontact gui freezes, and corrupts when minimizing/maximizing/etc. Viewing the folder in Kmail works perfectly fine however. Running Kontact from the commandline does not produce any (helpful) output, so I'm at a loss. The folder is a custom folder on an IMAP server. STEPS TO REPRODUCE 1. Start Kontact 2. Visit one particular folder. OBSERVED RESULT 1. Gui freeze EXPECTED RESULT No freeze.
