This is almost certainly a failure to properly find and execute mozilla-runtime. This may be due to the XULRunner/Firefox split that distros use, failure to ship mozilla-runtime, failure to find it in the expected location, or even something really dumb like it isn't marked executable. An strace would probably tell you where we're looking for it.
