Hi CBX team
Just running the new Linux version (Alpha4) of the wallet released above - after a bit of fiddling managed to get a repeatable
Segmentation Fault (Core dumped) error message by exiting the wallet during synchronisation - It re-started ok and after a re-scan I was back in business
I seem to be able to trigger the Seg fault by going into Settings, Options and selecting 'Show Master Nodes Tab' - quitting the wallet at this point repeatably raises the described segmentation fault on the command line
Nothing more useful in the debug log i'm afraid, but defo an unhanded exception somewhere - might be to do with the omission of the BPN stuff but regardless a seg fault it never a welcome error at any point of development
Home that helps squash a potential bug or two

Cheers
