Firefox 18.0 crashes at startup with Music Player Minion enabled #127

Open GoogleCodeExporter opened 9 years ago

GoogleCodeExporter commented 9 years ago 
What steps will reproduce the problem?
1. Install or update to Firefox 18
2. If you have MPM enabled, FF will crash at startup
3. Even if you reinstall MPM, it will still crash

What is the expected output? What do you see instead?
I expected to continue using MPM, but had to disable it because FF 18 won't 
start with it.

What version are you using? On what operating system?
Music Player Minion: 2.2 (and also tried with the patched 2.1.3 from 
http://www.gargan.org/en/Mozilla_Extensions/Music_Player_Minion/ )
Firefox: 18.0
Music player Daemon (MPD): 0.16.6
OS: Windows 7

Please provide any additional information below.

Here is a list of changes to FF 18 that could have an impact on MPM:

Also, while restarting firefox with MPM enabled, it seems that everything is 
fine for about 1 second but then firefox crashes. I had to disable the add-on 
to continue using FF.

More information:

The crash only appears to happen when MPM tries to successfully connect to a 
MPD server. All the windows, preferences, etc, seem to work fine when the MPD 
server is not available.

When trying to connect to a MPD server, it crashes with these two errors:

Error: this.docShell is null
Source File: chrome://global/content/bindings/browser.xml
Line: 323

Error: TypeError: aUrl is undefined
Source File: chrome://browser/content/urlbarBindings.xml
Line: 642

I have the same issue on Firefox 18 and Windows 8. On Firefox 18 and Debian it 
is OK.
On W8 it starts to crash when browsing files.

I don't know what's musicpm (sorry), but know one of your bugs.

With clean firefox installation, without opening any new tab,
after leaving urlbar i got this error message in error console:

("Error: TypeError: aUrl is undefined
Source file: chrome://browser/content/urlbarBindings.xml
Line: 642
")

It's still in firefox 21.0a1, remember it since few relases ago,
now just confirming it.

Firefox source file: chrome://browser/content/urlbarBindings.xml:

      <method name="_parseActionUrl">
        <parameter name="aUrl"/>
        <body><![CDATA[
          if (!aUrl.startsWith("moz-action:"))
            return null;

          // url is in the format moz-action:ACTION,PARAM
          let [, action, param] = aUrl.match(/^moz-action:([^,]+),(.*)$/);
          return {type: action, param: param};
        ]]></body>
      </method>

probably shall be:

      <method name="_parseActionUrl">
        <parameter name="aUrl"/>
        <body><![CDATA[
          if (!aUrl || !aUrl.startsWith("moz-action:"))
            return null;

          // url is in the format moz-action:ACTION,PARAM
          let [, action, param] = aUrl.match(/^moz-action:([^,]+),(.*)$/);
          return {type: action, param: param};
        ]]></body>
      </method>

https://bugzilla.mozilla.org/ is right place to solve it,
providing accurate information - what probably I may do
one day..

It seems that it was a Firefox bug after all since MPM started working again 
with FF 19.0.2
