Keepass2 hangs; Will not close or accept entries

[David Oxland]

Keepass2 hangs every in Ubuntu 16.04 time I open it; will not close with killall or unity buttons.
will not close by any method;(except system shutdown.
Menu buttons and words greyed out and inoperable.

Did work for a couple of short sessions.
 Will not import .kdb file from KeepassX usless in a Windows environment. I'm only Ubuntu 16.04

[Launchpad Janitor (janitor)]

Status changed to 'Confirmed' because the bug affects multiple users.

I have the same problem. When using auto-type or when double-clicking on an entry to copy the password to the clipboard, KeePass2 hangs and I have to kill it.

Restarting used to fix the problem, but unfortunately no longer.

I am using Lubuntu 16.04 64-bit.

Will not import .kdb file from KeepassX unless in a Windows environment. Word usless replaced with unless.
I'm a linux only user.

Further experimentation seems to indicate that there is a problem with copying to the clipboard.

KeePass2 works fine until I double-click a username or password, at which point it hangs.

If I instead open the entry, highlight the username or password, and copy, then I can paste it into certain applications (such as gedit, pluma or leafpad), but not others (such as gnome-terminal).

To further confuse things, sometimes KeePass2 suddenly starts to work properly after killing and restarting it multiple times.

Running KeePass2 from the terminal does not produce any error messages.

@doxland — I did not import from KeePassX, in case that helps.

[Paddy Landau (paddy-landau)]

After some experimentation, it seems that KeePass2 will work correctly if, after starting it for the first time, it is left alone for a couple of minutes before using it.

Perhaps there is some type of database reorganisation that takes place each day, and causes KeePass2 to hang if used before it is complete?

@doxland Does this information help you?

[Paddy Landau (paddy-landau)]

I have further information.

For me, I find that this problem occurs only with the plugin QuickUnlock installed.

When QuickUnlock is installed, this problem recurs when using KeePass2 prior to the automatic lock — as set in Tools > Options > Security > Lock workspace after KeePass inactivity (seconds).

After the lock has activated for the first time, KeePass2 then works properly.
