Linux bitsharesGUI Segfault on Start
I just grabbed bitsharesGUI-0.6.1-linux-x86_64.tar.gz, moved away ~/.BitShares and ~/.config/BitShares, and fired it up.

@djthread Can you run this in gdb and give us a stack trace of the crash?
Cheers, Vikram. Thanks for looking at this.
Perhaps this is what you're looking for?

I did a trace of all threads, too. It's a bit unwieldy... the top bit went off my term buffer, even. I don't think that part is important, though.
http://threadbox.net/tmp/thread-apply-all-bt.txt
Some Googling found a vaguely similar backtrace in another application on Mac, see https://bugreports.qt.io/browse/QTBUG-33113
but it looks like there is about ~50% chance that is a different Qt bug entirely.
I also found https://github.com/CESNET/canl-c/issues/7 -- apparently one OpenSSL user is having issues with crashes due to multiple calls to SSL_library_init() from multiple threads. I'm wondering if maybe SSL_library_init() is called by both qt main thread and some other thread. Maybe the Qt client's main() needs to call something that forces SSL_library_init() to happen before additional threads are created.
@theoreticalbts That's an interesting find. If both Qt and FC are initializing OpenSSL, we may have problems.
Most likely this is caused by using https to fetch the manifest. If we bounce that fetch task back out to the main thread, it may circumvent this issue.
Will assume addressed by https://github.com/BitShares/qt_wallet/compare/c28c0947e5...f941bc3a11 until we hear otherwise.
Still happening: https://github.com/BitShares/bitshares/issues/1519#issuecomment-96797237
