I have been running firefox2.0 along firefox1.5.0.7 for quite a while;
the former was designed to be compatible with the latter, installing
everything under firefox2. After the latest bunch of security fixes
for firefox I decided to update. I thought it would be just a matter
of removing firefox2, leaving firefox1.5.0.7 in place - it being the
package all the Gnome packages depend on.

The new firefox2.0.0.1 has been created to replace firefox1.5.0.7,
using the latter's destination paths etc. Removing 1.5.0.7 lege artis
would have lead to recompilation of quite a lot, so I forced it and
installed firefox2.0.0.1. It dumps core on me. I had to go back to
1.5.0.7 and 2.0 (I had them saved with pkg_tarup).

I then had a look at the Makefile and saw the MOZILLA variable; I
rebuilt firefox2 with MOZILLA set to firefox2 and installed it (just
normal make install). The component registration at the end failed:

=> Automatic manual page handling
=> Running POST-INSTALL script actions

No wonder under gdb I get (no symbols):

Any ideas? (meanwhile back to firefix2.0).
