Crashes are still threre for me with 2.2 and 2.3 (homepage of developer).
However, i was able to get rid of them by compiling the plugin myself form svn. The crucial step seems to be, that you build libkdewallet.so so please first build this liib with the provided cmake file and pack the plugin afterwards.

I do not need to disable any jit-compiler in FF or any other special settings.

This review is for a previous version of the add-on (2.2.1-signed.1-signed). 

I do compile each of the libraries before packing, If you only do that and it works for you it's just luck. We have an open bug on moz-dev about this, the problem is still pointing to a bug in the new JIT compiler, or at least, some incompatibility with it and foreign libraries.
