Delayed 'Gesture not found' notices crashing Macs

Anyone else experiencing this?

Before today's asset issues, I have had problems creating and keeping gestures in my inventory. The client has always given me 'Gesture cannot be loaded' notices. They're not integral (yet) to any products I create, so when they come up, I don't mind so much.

BUT.

Today with the asset problems, these notices are coming up about 4-5 mins *after* logging (not immediately as they usually do), and when they do, they *immediately* crash my client (Firstlook AND Main client).

I am running a Mac PowerPC PB, 1.67Ghz, 1.5GB RAM. ATI Radeon 9600 XT video card.

//Edit #2: May be region specific (in this case, I was affected in the Drax sim). Have been able to get the notices by logging in from another sim without crashing. Yet.
