Version: 1.13.0 (using KDE 4.4.0) OS: Linux Installed from: Gentoo Packages When I load a previously saved html message from disk (mbox file). kmail can only display the text message, not the html message. If I open that mbox file in thunderbird, the mail looks as expected (like the original mail).
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.
