Today while checking something else I noticed that on the 15th TUV released 'firefox stability update' and 'thunderbird stability update' packages. Reading the announcements (and bugzilla entries) I see the following statements: https://rhn.redhat.com/errata/RHBA-2008-0147.html A stability bug was found in the Red Hat Enterprise Linux 5 Firefox packages released in RHSA-2008:0103. These packages were linked against an incorrect version of a library which would cause Firefox to randomly crash while the browser was in use. https://rhn.redhat.com/errata/RHBA-2008-0148.html A stability bug was found in the Red Hat Enterprise Linux 5 Thunderbird packages released in RHSA-2008:0105. These packages were linked against an incorrect version of a library which would cause Thunderbird to randomly crash while in use. Now in both cases the updated srpm includes an additional patch but no *obvious* changes to the libraries that the code will link against. The only explanation I have managed to come up with is that they have changed their build-environment in some way - different default packages in their brewbuilder setup perhaps. Does this seem at all likely? Does anyone have a better explanation of what the incorrect-library linking issue might actually be? Now we have users complaining (some quite bitterly) about random crashes of both firefox and thunderbird and this *seems* to have got noticably worse about 2 months ago - at least judging by the number of reports we get via our help-desk. Personally I've not seen any problems but then I mostly still use the seamonkey on SL3x and don't touch tbird except to check that it runs :-) Anyway tomorrow I'm going to try building ffox/tbird from the updated srpms in the hope that either my rpm build-environment (I've not got anything fancy yet) is good-enough or the extra patches help in some way. -- Jon Peatfield, Computer Officer, DAMTP, University of Cambridge Mail: [log in to unmask] Web: http://www.damtp.cam.ac.uk/
