Crash when using keyboard shortcut CTRL-SHIFT-M under Windows

[markusbuschhoff]

I use the keyboard shortcut CTRL-SHIFT-M to open SSH sessions via putty. However, the whole shortcut handling under Windows (on two different installations) does not work correctly:

Description

• right after starting KeePass2, the shortcut shows no reaction at all
• only after opening the "KeeAgent" shortcut menu (no need to select anything here), the shortcut becomes active. This bug has been there for some versions now, I got used to it.
• now, after context menu opening, with KeeAgent v0.12.1.0, using the shortcut (not the menu) the first time causes an unhandled exception (see below)
• when using the context menu directly, this exception never occurs
• only after once having used the context menu, the shortcut works as expected, too

Steps to reproduce bug

• freshly start KeePass2
• select an entry with KeeAgent functionality
• hit CTRL-SHIFT-M -> no reaction (bug 1)
• open the KeeAgent context menu of this item (not selected anything), dismiss the menu
• hit CTRL-SHIFT-M:
  • former versions: works as expected
  • now: Unhandled exception message (bug 2)

Version info

KeePass: 2.47 (64bit)

KeePassLibC (1x File Support) :1.39 (0x1B7)

************** JIT-Debuggen **************
Um das JIT-Debuggen (Just-In-Time) zu aktivieren, muss in der
Konfigurationsdatei der Anwendung oder des Computers
(machine.config) der jitDebugging-Wert im Abschnitt system.windows.forms festgelegt werden.
Die Anwendung muss mit aktiviertem Debuggen kompiliert werden.

Zum Beispiel:

<configuration>
    <system.windows.forms jitDebugging="true" />
</configuration>

Wenn das JIT-Debuggen aktiviert ist, werden alle nicht behandelten
Ausnahmen an den JIT-Debugger gesendet, der auf dem
Computer registriert ist, und nicht in diesem Dialogfeld behandelt.
