[Thunderbird] Associating external Mac OS X application to mime types

Dear All,

Just after installing Thunderbird 0.4 on Panther, I tried to bind 
'usual' mime types to external applications.

Example: PDF file to preview or MS word file to MS word

While I could do this with MS Office applications, I was unable to do 
the same with most of Apple delivered ones (preview, iTune, etc.).

After investigating a bit, I found out about the notion of Application 
bundle in Mac OS X and I suspected that Thunderbird preferences could 
not handle them properly. No mention of this in the Mozilla FAQ thqt I 
could read. Bugzilla did not contain such a bug report.

So I posted a bug

<http://bugzilla.mozilla.org/show_bug.cgi?id=232220>

but thinking about it, I find this *so* obvious that I have two 
additional questions:

- is there any workaround that I would have missed?
- is the behavior the same with Mozilla 1.6
