Comment 7 for bug 801414

Bug confirmed on Ubuntu 12.10 x64.
Please note that, in fact, the open database dialog shows up everytime the database is locked when the window is minimized, not when you lock it from the window for instance.
For example, if I wish to launch it from the command line with, let's say, the --lock-all option, if an instance of keepass is already running minimized, the dialog will show up, but if the window is maximized and I run the same command, the database locks up and the window minimizes without showing the dialog.
I've been working on a workaround to lock the database after a few minutes of global user inactivity (since the checkbox can't be checked on Ubuntu) with xautolock, and this dialog showing up everytime I lock the database minimized is a pain in the ass...
Wait and see.
