286353 - downloaded files are saved with an extra file extension appended

Status: RESOLVED DUPLICATE of bug 270159

(Toolkit :: Downloads API, defect)

Description

[Donnie Roberts]

User-Agent:       Mozilla/5.0 (X11; U; Linux i686; en-US; rv:1.7.6) Gecko/20050225 Firefox/1.0.1
Build Identifier: Mozilla/5.0 (X11; U; Linux i686; en-US; rv:1.7.6) Gecko/20050225 Firefox/1.0.1

When saving files to a mounted vfat filesystem via the "Save all files to this
folder" preference, an extra file extension is appended to the saved files. I
end up with files ending in .zip.zip, .mpg.mpg, .pdf.pdf, .tar.gz.gz, etc.


Reproducible: Always

Steps to Reproduce:
1. Edit->Preferences->Downloads. Set "Save all files to this folder" to point to
a mounted vfat directory.
2. Click on a downloadable item and choose "Save to Disk".
3. Look in the Download Manager window and the filesystem for the downloaded file.
Actual Results:  
The filename has an extra file extension appended to it, corresponding to its
mime type.

Expected Results:  
The filename should not have an extra file extension appended to it.

Works as expected in Firefox 0.9.3 through 1.0rc2
Misbehaves in Firefox 1.0 and 1.0.1

Works as expected when saving to reiserfs and tmpfs filesystems.
Works when "Ask me where to save every file" preference is chosen and saving to
mounted vfat partition.

See Bug 270159 "Download manager adds extension regardless of file's own 
extension" and friends, but I have not seen an exact dup of your report.
