reindexing may help...

./bitshares_client --rebuild-index

Sorry should have been more clear.
Tried that and it doesn't work.  As soon as the blockchain is synced it crashes.

I was trying to demo how easy it is to use bitshares today.
Every time I launched the app it crashes with...


QObject::startTimer: Timers can only be used with threads started with QThread
QPaintDevice::metrics: Device has no metric information
Segmentation fault


This occurs after the app launches and after login, timing seems very random but always after those 2 events.
If I had to guess I would say you're trying to paint a balance update from a network thread, since the only thing I did notice is that it always seems to have just finished syncing the blockchain.

0.8.0 Never synced correctly on this machine so I downloaded the binary release of 0.8.1 from github releases.

It has worked great for at least a week.
To be clear, it NEVER did this before yesterday. 
I've installed nothing new on my system in over a week and I run the client at least once a day for several hours.

It is possible that a system update came down and updated QTlibs though.  I am running Kubuntu which is kinda QT heavy, but I'm not rolling back my system libs to test.

Thanks!
