232220 - (app_bundles) Unable to associate a file type to an application bundle under Mac OS

Status: RESOLVED DUPLICATE of bug 222563

(Thunderbird :: Preferences, defect)

Description

[Emmanuel BUU]

User-Agent:       
Build Identifier: Mozilla Thunderbird 0.4 (20031205)

In the preference panel, 'Attachement' item, when trying to associate a file type (e.g. JPEG image) 
with an application by pushing the "change action" button, most of applications (e.g. Moc OS X 
Preview) appears dimmed (disabled) in the file chooser. It is not possible then to associate a file 
time with such an application 



Reproducible: Always
Steps to Reproduce:
1. Launch prerefence panel with menu 'Mozilla Thunderbird' / Preferences
2. Select 'Attachement' item on the left
3. Try to associate JPEG image file type with Mac OS X Preview application.
Actual Results:  
The preview application (and all others in the Application directory) except MS Office are dimmed 
and cannot be selected.

Expected Results:  
Every valid Mac OS X application should be eligible to be bound with a given file type.

It seems that all the applications that cannot be bound to a file type are in fact Mac OS X 'Bundle'. 
In MAC OS X, well formed applications are in fact directories with an .app extention and a special 
permission bit. They are called bundle ; actual binaries are residing in a subdirectory. The Mac OS 
finder hides all theses subdir and handle the xxxx.app as a single entity.

This bug is most likely be Macintosh specific.
