keepass2 crashes when opening database

[Bartosz Marek]

When I open keepass2 on my lubuntu desktop, and next i try to open base, I've got System.Text.DecoderFallbackException
Full log:

I've found similar mono error, but I install mono-complete and problem still exists.
My system: amd64 lubuntu 12.04, packet: 2.19+dfsg-1~ppa1~precise1_all.deb
I except well workin' keepass

cheers

was keepass never working or is this a new issue?
if its new, can you open an older backup?

if possible to test is can the database be opened on windows?

[Bartosz Marek (bartosz-marek)]

Hi,
on this machine keepass has never started properly - I tried half year ago. For now I've virtualbox with winXP, keepass 2.17 and this file opens properly.

cheers

I've just started keepass with strace - results in attachment. Maybe it helps, I hope.

[Julian Taylor (jtaylor)]

it is very hard to debug this without reproducing the issue.

It would be great if you could produce a dummy database that causes the issue and attach it to the bug.

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

[Zsoltee (zsoltee-the-programmer)]

It affects me too. Please help me, I can't access my passwords needed for everyday life. Thank you in advance!

As Julian stated, we cannot fix the bug unless someone shares a database that causes the crash. The crash happens while decoding UTF8 text. There is probably a bug in the Mono framework that need to be fixed because it thinks there is some invalid character sequence in your database.

[Bartosz Marek (bartosz-k-marek)]

Gents, now I'm using 2.25 version on lubu 14.04 and It's works perfectly. I think you can close it with workaround status.

It appears that this crash is caused by having a binary ~/.recently-used file. See http://sourceforge.net/p/keepass/bugs/1358/ for more information. You can delete or rename ~/.recently-used to prevent the crash.
