not sure what the raise was trying to do;
note that relevant exception handling is done at:
https://github.com/spesmilo/electrum/blob/bba8a272e78ae8961dffd37060801bf28b934dd9/electrum/gui/qt/main_window.py#L1213-L1217
although note the TODO in main_window.on_error: would be nice to propagate some of the exceptions to the crash reporter
