Version: 1.12.3 (using 4.3.3 (KDE 4.3.3), Gentoo) Compiler: i686-pc-linux-gnu-gcc OS: Linux (i686) release 2.6.31.7 The amount of emails within a subfolder of my inbox is 0, if the last email of the previously non-empty subfolder was deleted otherwise an empty sring is displayed instead of 0. I'd expect aleways a non-negative number.
Thank you for taking the time to file a bug report. KMail2 was released in 2011, and the entire code base went through significant changes. We are currently in the process of porting to Qt5 and KF5. It is unlikely that these bugs are still valid in KMail2. We welcome you to try out KMail 2 with the KDE 4.14 release and give your feedback.
