I'm seeing what I *think* is the same crash in the 1999-07-14-08-M8 linux opt build from mozilla.org, when I open the sidebar, since res/samples/bm-panel.xul and res/samples/related-panel.xul still didn't use chrome URL's in that build. I get rid of the crash if I replace their stylesheets with chrome URL's, but can get it back by replacing chrome://global/skin/ in related-panel.xul with res:/samples/xul.css (which no longer exists). The stack traces look very similar, but not quite the same (#1 and #2 differ, but that could be debug/opt or something else weird). Here's the top of mine from the opt build: #0 0x405cf5d4 in main_arena () b#1 0x7264 in ?? () #2 0x400e937e in NS_ShutdownINetService () #3 0x400c8ba3 in net_CallExitRoutine () #4 0x400cabe0 in NET_GetURL () #5 0x400e80aa in nsNetlibService::OpenStream () #6 0x40204428 in nsDocumentBindInfo::Bind () #7 0x4020381d in nsDocLoaderImpl::OpenStream () This seems like a general XUL crashes if a stylesheet doesn't exist. Therefore, raising severity to critical. I can replicate in on other XUL files. For example, add a nonexistant stylesheet to res/samples/bookmarks.xul and go to Bookmarks|Manage Bookmarks. Same crash...

This appears to be another case of NS_NewUnicharStreamLoader calling its callback function synchronously (on linux only). I've added debug code to the CSSLoader to detect when that happens.

Pl. verify with Necko.

The original stack trace is from a non-necko build. Pls. verify this with the latest necko (tip) I also recently fixed the chrome:// and resource:/ problems we have been having with using inconsistent styles. So that should also help.

akkana, can you verify this fix. I really don't know what is supposed to happen in this case.

Well ... it doesn't crash any more, but instead it prints: CSSLoaderImpl::DidLoadStyle: Load of URL 'chrome://global/skin/' failed. Error code: 65535 Got the event queue from the service Calling gdk_input_add with event queue Error: Can't load: file:////builds/wed/thu/mozilla/dist/bin/chrome/global/content/default/tasksOverlay.xul (8000ffff) nsWidget::RealizeSignal(0x812eac8) and then hangs waiting for a nonexistant window to come up. I'm not sure that hanging is better than crashing. (It would be helpful if a QA person could try this in an optimized build and see what messages are printed out and whether they are clear.) It really ought to print an error message then exit.

under what conditions might the files be missing? does't sound like something we need to hold m9 for.

No, don't hold M9 for it.

Clearing FIXED resolution due to reopen of this bug.

David said he didn't have enough bugs. Its a dup of one of his bugs...

My hands have deteriorated to the point where I can no longer type. I need help. If you think you can fix this bug on your own, please take it away from me. If you'd like to volunteer to be my hands for a specific bug, then I'll be happy to come up to your cube and sit with you and fix the bug (assuming you have the patience for that).

moving to m14

resolving as wfm per hyatt.

Bulk move of all Networking-Core (to be deleted component) bugs to new Networking component.

sorry fot the spam, changing QA contact.
