From Bugzilla Helper: User-Agent: Mozilla/5.0 Galeon/1.2.5 (X11; Linux i686; U;) Gecko/20020809 Description of problem: when mozilla is installed before the new (current) glibc is installed, /usr/lib/mozilla-1.0.1/regxpcom can not be run and /usr/lib/mozilla-1.0.1/component.reg can not be created. Both mozilla and galeon will fail to run if this file is missing. Version-Release number of selected component (if applicable): How reproducible: Always Steps to Reproduce: 1. start with redhat 7.3 2. upgrade mozilla/galeon with all dependencies but not glibc (which is not an explicit prereq) 3. try starting mozilla or galeon 4. rpm -V mozilla 5. run /usr/lib/mozilla-1.0.1/regxpcom Actual Results: mozilla/galeon cannot start (failed to initialize mozilla libraries) because the component.reg file is missing or empty. rpm -V mozilla shows something wrong with component.reg. /usr/lib/mozilla-1.0.1/regxpcom gives a library error, and cannot run. Expected Results: component.reg should be remade by /usr/lib/mozilla-1.0.1/mozilla-rebuild-databases.pl (in the post-install scripts). The script is run, but the binaries don't work with older glibc's. Additional info: This is not a problem in a full install or full upgrade. It can give problems in manual upgrade (because the rpm prereqs don't force the correct installation order and dependencies).
