Bug 7762 – Immediate Safari crash when visiting RooTV pages

• Component: Plug-ins
• Status: RESOLVED INVALID

[Sulka Haro]

All visits to RootTV immediately crash Safari, both the latest release version and the latest nightly. I guess based on the crash report this could be in the WMV plugin, however Firefox is running the same plugin and it doesn't crash on the site so I consider there's some issue within Safari / Webkit. I have the latest Windows Media Player 9 installed from http://www.microsoft.com/windows/windowsmedia/player/mac/mp9/default.aspx

Exception:  EXC_BAD_ACCESS (0x0001)

I couldn't reproduce the crash with 2.0.3; however, I got an assertion failure on ToT:

Reporter, could you please attach a complete crash log (preferably with loaded modules, too)?

Full crash log

Full crash log using last night's nightly (420+). I also re-verified that I can browse through the site and the videos play correctly when using Firefox.

>  0x618b000 -  0x618ffff net.telestream.wmv.plugin 1.0	/Library/Internet Plug-Ins/Flip4Mac WMV Plugin.plugin/Contents/MacOS/Flip4Mac WMV Plugin

This seems to imply that it's actually a Flip4Mac plugin, not the one from Microsoft. Also, the current version of Flip4Mac is 2.0.2, so 1.0 must be quite dated.

I cannot reproduce the crash with Flip4Mac 2.0.2 either. Could you please double-check?

[Sulka Haro]

The crash went away after upgrading the video component. I have no idea where the 1.0 version came from - I guess it was installed as part of something ages ago and has migrated itself over through the time and computer upgrades.

I'm slightly curious though on why Firefox had no issues with the site..? I guess WM plugin behaves differently on the browsers.

The same assertion failure as in comment 1 happens in bug 7808.
