I made a simple Linux RPM bundle to install and launch Mozilla Thunderbird V2 on SLES11sp1
The RPM installs fine, but nothing is launched (I did configure it to launch the binary of course).
In the log it says it tries to launch /usr/bin/thunderbird, but nothing happens.
Here is part of the log in debug mode:
