Mendeley and KDE
Mendeley is a very convenient bibliography tool. It keeps track of all your references, you can easily import from tons of sites and it backs up your collection on their servers. It also works on all major operating systems thanks to the Qt library.
Their latest builds had a bug on KDE systems though: you can’t open a pdf in an external viewer, which is rather annoying because the internal one is rather limited.
Now it appears that you can solve this bug by remove the Qt library files that come with the mendeley installation. Just add .bak to all files that have “Qt” in their name in the mendeley install folder.
Mendeley will now use your systems Qt libraries and “open in external viewer” will work. As an added benefit Mendeley will now also better integrate in your desktop visualy.
