218826 - TypeError + stuck dialog when clicking URLs in messages

Status: RESOLVED DUPLICATE of bug 226071

(Thunderbird :: Mail Window Front End, defect)

Description

[Aaron Barnhart]

User-Agent:       Mozilla/5.0 (Macintosh; U; PPC Mac OS X Mach-O; en-US; rv:1.5b) Gecko/20030827
Build Identifier: Mozilla/5.0 (Macintosh; U; PPC Mac OS X Mach-O; en-US; rv:1.5b) Gecko/20030827

Following dialog appears occasionally when clicking URLs in mail messages:
"Error launching browser
window:TypeError:Components.classes['@mozilla.org/appshell/component/browser/instance;1']
has no properties"

Furthermore, dialog won't close when clicking OK (application switching solves this)

Reproducible: Sometimes

Steps to Reproduce:
1. View message in three-pane mode
2. Click on URL link
3.

Actual Results:  
Dialog appeared.  Wouldn't go away until I switched here (to Mozilla) and back
to Thunderbird.

Expected Results:  
Switched to Mozilla and opened selected URL.

Error occurred often under 0.1 -- tried it as soon as I installed 0.2 and
reproduced error immediately.

this is a dup of the unix xremote bug if someone wants to dup it.

mostly a 'me to' msg, except i wish to add that i notice that the dialog box can be made to go away 
if all other windows are closed ... except that then there's no way to get back into the mailreader 
window (which i know i already saw entered as another bug, don't remember the number).

This same bug occurs on my machine (Mac OS X 10.2.6) when any application
running tries to open a url while Thunderbird is open. Thunderbird (0.3
20031013) recives focus and this error message apears "Error launching browser
window: TypeError:
Compnents.classes['@mozilla.org/appshell/component/browser/instance;1'] has no
properties"
 The error message is closeable if I click on the the title bar of the top
Thunderbird window and then back to the error message.

Reproducible: 100%
Thunderbird must be running already.
