Google Talk plugin may crash for uses on OSX 10.6.8

Thanks to your reports, we’ve identified an issue affecting the Google Talk plugin in Macintosh OSX 10.6.8 which causes it to crash unexpectedly. The crashes in this case can happen between the greenroom and joining a Hangout, after a Hangout or after a 1:1 call. This particular crash is caused by an incompatibility with Rogue Amoeba’s Audio Hijack Pro software.

While both we and Rogue Amoeba are working to resolve the issue, you can use the following as a workaround in the meantime:

    1. Start Audio Hijack Pro
    2. Under the Audio Hijack Pro menu, click Install Extras....
    3. In the Instant On feature, click Instant On Preferences....
    4. Click the + button to add an exclusion.
    5. Add the following, /Library/Application\ Support/Google/

Doing so should resolve Talk plugin crashes due to this incompatibility. We’re still investigating other types of crashes, however, so please keep reporting them to us as they happen.
