I've imported the WO wallet on 3 computers now with similar results. On rig 2 I got the wallet imported and scanned but it would crash frequently (with 30 minutes) and now does load without crashing. On rig 3 I've done a clean install of Ubuntu 12.04, updated and installed bitcoind and qt from the ppa, synced the blockchain and I'm having similar symptoms as rig 2 and 1 now.
I moved back to using 0.88.1 on rig 1 and it hasn't crashed after a few days.
Would it make sense to try to reimport (from the paper fragments I have) and export the WO wallet and see if that works better or is that unlikely to do anything different?
Do you mean this WO is ages old? I thought you had it exported from your recently restored wallets. If it is very old, now I really want to take a look at it.
Someome just recently sent us a WO that crashes Armory. I don't know if its yours but I'll be getting on it soon. I'm not gonna insist to see your WO until I'm done with the current one, however it may be very interesting. If anything don't delete it.
As for your test, you should try with a freshly derivated WO.
It wasn't me who sent you the WO wallet. I will try with a freshly exported WO wallet from the backup and update you. I will keep a backup of the WO wallet that's crashing.
It's not an old wallet. The first tx I have in there is early Dec. 2013 so I imagine I made it with whatever Armory version was current then.
As an aside, using 0.88.1 is working well right now.
