You have these problems with Thunderbird 1.0.6 too?

I have the same problem with 1.0.6 -- well, it doesn't dump core.  On startup,
it just spins for awhile, then gives me the prompt back with no error.

Same proble with 1.0.6 on FC4 ppc. ./thunderbird-bin report Segmentation Fault

Here's Thunderbird 1.0.6 output from the terminal:

[dennyv@ibook ~]$ /usr/lib/thunderbird-1.0.6/thunderbird
/usr/lib/thunderbird-1.0.6/run-mozilla.sh: line 159: 22979 Segmentation fault  
 "$prog" ${1+"$@"}

Lunching /usr/bin/thunderbird nothing happens

I guess 1.07 doesn't work either?

(This is a mass update of bugs which have been in the NEEDINFO state unmodified
for over a year and have not been confirmed for a still supported version of
Fedora Core.)

Closing per lack of response to previous request for information.
This bug was originally filed against a much earlier version of Fedora
Core, and significant changes have taken place since the last version
for which this bug is confirmed.

Note that FC3 and FC4 are supported by Fedora Legacy for security
fixes only.  Please install a still supported version and retest.  If
it still occurs on FC5 or FC6, please reopen and assign to the correct
version.  Otherwise, if this a security issue, please change the
product to Fedora Legacy.  Thanks, and we are sorry that we did not
get to this bug earlier.

I believe this was fixed long ago anyway. Thunderbird on ppc32 works fine.
