"Component returned failure code: 0x80520015 (NS_ERROR_FILE_ACCESS_DENIED) [nsIFile.create]" nsresult: "0x80520015 (NS_ERROR_FILE_ACCESS_DENIED)" location: "JS frame :: file:///usr/lib/xulrunner-1.9/components/nsHelperAppDlg.js :: anonymous :: line 271" data: no] Reproducible: Always Steps to Reproduce: 1. Download a file 2. Use "Save to disk" instead of "Open with" 3. Select a destination directory that is not writable to the user Actual Results: There is no notification of failure to the user but a message in the console (if FF3 was started from a terminal): *** exception in validateLeafName: [Exception... "Component returned failure code: 0x80520015 (NS_ERROR_FILE_ACCESS_DENIED) [nsIFile.create]" nsresult: "0x80520015 (NS_ERROR_FILE_ACCESS_DENIED)" location: "JS frame :: file:///usr/lib/xulrunner-1.9/components/nsHelperAppDlg.js :: anonymous :: line 271" data: no] Expected Results: A dialog box notifying that the file was not saved. The fix is actually fairly simple, in "nsHelperAppDlg.js", the call to aLocalFile.create() must be protected by a try/catch.

Bug 429827 should have fixed this.

Thanks for the patch anyways, though, Olivier!
