2.6.19 on bionic: QIF import wizard hangs when manipulating account tree

[Ryan C. Underwood]

Occasionally when manipulating the account tree attempting to assign transactions to existing accounts, the dialog just hangs when the "expand tree" widget is clicked on. It seems to be related to possibly manipulating the dialog too fast, but I really have no idea. It is very frustrating because you lose the entire state of the import (all transactions) when this happens.

[Ryan C. Underwood (nemesis-icequake)]

I've also noticed that this happens occasionally if I double-click on the line item itself - the whole dialog hangs. It seems to be some kind of race condition since it's never the same item causing the problem twice.

[Ryan C. Underwood (nemesis-icequake)]

Also cannot reproduce under valgrind, which indicates that a race condition is to blame (it's running much slower there).

[Ryan C. Underwood (nemesis-icequake)]

Was finally able to reproduce under valgrind with the OFX/QFX import plugin!
