100232 - DL'ing BMP image without associated helper application crashes mozilla

Status: VERIFIED DUPLICATE of bug 97970

(SeaMonkey :: UI Design, defect)

Description

[G. Todd]

On Linux i686; en-US; rv:0.9.4 Gecko/20010913 if no helper application is set
for image/bmp or image/* then visiting a URL which points at a BMP image, eg:

http://dot.kde.org/1000526169/1000558013/1000586236/shape32.bmp

causes mozilla to crash. This may occur with other image types (TIF etc) but has
not been tested.

Steps to reproduce:
------------------

1) Clear associated helper applications (which is the default) and visit the
above URL 

Results:
-------

Mozilla crashes


Expected behaviour:
-------------------

Mozilla should offer a dialog box to choose or permanently set an associated
helper application


Note that if the helper application is set (to xv or display on Unix) the
behaviour is correct so a workaround is to have helper applications defined. The
more complete fix is left as an exercise to the most excellent Mozilla developer
crew!  BTW The talkback report associated with this is TB35439096Q

Probably bug 99057.  Please retest once that's fixed...

Asa, if you can look at the stack trace and comment, that would be great.

called "shape32.bmp" trying to view it crashes Mozilla. This is because there is
no helper application defined for BMP files. If there is one defined
