The Software-Installation-Pop-Up-Window comes up, but there was no progress. xpi-install was o.k. in 2006061220, broken in 2006061309. I have missed the Builds between, so I can't cutdown the Regression-Range. Error Console throws: Error: uncaught exception: [Exception... "Component returned failure code: 0x80004002 (NS_NOINTERFACE) [nsISupports.QueryInterface]" nsresult: "0x80004002 (NS_NOINTERFACE)" location: "JS frame :: chrome://communicator/content/xpinstall/xpistatus.js :: onLoad :: line 131" data: no] Probably this was an Duplicate for Bug 341362 but I am not sure, because I don't know the differences between the Extension-Manager an install.js very much. Reproducible: Always Steps to Reproduce: 1. Install or unpack SM-Trunk 2006061309 2. Try to install *.xpi, example at https://bugzilla.mozilla.org/attachment.cgi?id=225411 3. Actual Results: The Extension won't install, unable to close Install-Popup Expected Results: The Extension should be install in SeaMonkey.

This looks like a dupe of 341362 - please try the patch there.

(In reply to comment #2) > This looks like a dupe of 341362 - please try the patch there. > Since bz has changed Bug 341362 to core and dom, I am quite sure that this one is an dupe. At mo I have no possibility to try the patch from there, I have wait for checkin and than I will try new Tinderbox-Builds. But I will mark this as Resolved=Duplicate for now, if this one will not be fixed by your patch it might be reopend. *** This bug has been marked as a duplicate of 341362 ***
