New profile, TST 0.14.2012021101 only (or 021001, haven't tested previous versions)
Default settings except "Auto Shrink tab bar" for Normal Window Mode

STR:
1. Open 2 unpinned tabs.
2. Move the cursor away from the tab bar so the bar is shrinked.
3. Move the cursor directly onto the active tab.

Actual result: An error message in the error console

Timestamp: 11/2/2012
Error: uncaught exception: [Exception... "Illegal operation on WrappedNative prototype object" nsresult: "0x8057000c (NS_ERROR_XPC_BAD_OP_ON_WN_PROTO)" location: "JS frame :: resource://treestyletab-modules/autoHide.js :: AHB_getMousePosition :: line 396" data: no]

If, in step 3, I first move the cursor to other parts on the tab bar then move to the active tab, no error messages is generated.
Opening only 1 tab has the same error but is not always reproducible.

I have not perceived any abnormalities caused by this error. Filing this issue for the record only.
Thanks.
