I have not yet tried 0.6.2, a quick look over the changelog yielded no relevant bugfixes. Did I miss anything?
Running under gdb is feasible, but I do believe that the segfault is not the issue here. I got them before as well, especially after receiving transfers.. almost 100% of the time, when both accounts are in the same wallet.
Still have not succeeded fixing this. I have thought about maybe eliminating the accounts from the wallet, letting it sync, and then rescan transactions, once the accounts are re-imported.
Is this possible?
