the latest nightly built kills the complete function of some extensions, i.e. 'Saft'.
Normally there's an error message or something like that but this time nothing appears and the plugin just does not get loaded (also does no longer appear a tab SAFT in the webkit-prefs).
Safari extensions, including Saft, are completely unsupported - you should contact the author of the extension.
This seems to be something new - with all the builts up to now it ALWAYS worked, this is the first time it's completely left behind! ;-(
If Saft were to be loaded, it would cause WebKit nightlies to crash on launch. See bug 22038.
As Matt says, Safari extensions are completely unsupported by Safari and WebKit. If you have any problems, please direct all complaints to the developer of the extension.
Trying to determine what changed between builds r37894 and r37990 that could cause Saft to crash WebKit. I'm fairly new to this, but is there a list of code changes between builds?
