Unfortunately we were not able to test GenomeBrowse on every distribution of Linux.
One thing to check is if you are running CentOS or Red Hat Enterprise Linux (RHEL) that you try our RHEL5 build of GenomeBrowse. The Lin64 build works on most modern Ubuntu/Debian distributions, but does has some known issues on RHEL distros that can cause crashes. I believe Fedora is a Red Hat Enterprise distribution.
From our download page click the RHEL 64 download button and try that.
If you should still have crashing issues with the new version please feel free to email us at email@example.com so we can help diagnose the issue.
