The only way to resolve this is -

/etc/default/keyboard

change

XKBLAYOUT="za" to XKBLAYOUT="us"

[Launchpad Janitor (janitor)]

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

[JP Meijers (jpm)]

All three my computers runs Ubuntu 12.04 64bit and all three suffers from this same issue since a few days ago. Intrestingly enough I also live in South Africa like the original bug reporter. I assume I also chose the za keymap at installation on all three.

[Bruce Pieterse (octoquad)]

I have two machines that get this segmentation fault. However, after changing XKBLAYOUT from "za" to "us" in
/etc/default/keyboard as mentioned above, remmina works after a soft restart.

I'm attaching my apport crash log, just in case there is some extra information that can be used.

[psypher (psypher246)]

changing my layout did not work. But I got it working by going to keyboard layout via dash and installing english US. then the keyboard layout indicator appears at the top. I select English US on there and remmina starts.

This problem is still occuring in 12.10. Has there been any work done? Please can it be assigned?

Thanks

[psypher (psypher246)]

Please can there be some attention to this bug, it has been ongoing for over a year. Any South Africa users trying to use the default remote desktop app in Ubuntu clicks on the app and nothing happens. This is not good for all those users who are trying out Ubuntu and I know that many Schools in SA use Ubuntu as well.

[Bruce Pieterse (octoquad)]

I have compiled the latest version from git and remmina seems to run fine if the RDP protocol is not installed and XKBLAYOUT="za". At this point I'm assuming FreeRDP might be the cause of the problem. Currently having an issue building the remmina-plugins but I will keep trying.

[psypher (psypher246)]

Yes freerdp is the problem, cannot be run with ZA set

[Ian Beardslee (ibeardslee)]

I'm getting this problem as well in Raring 13.04. I have XKBLAYOUT="mao".

And if I "sudo apt-get purge remmina-plugin-rdp" it starts fine. pretty much a definite that the RDP plugin (freerdp?) is the problem with it.

[Emelar (martin-rothbaum)]

I'm getting what looks like the same crash on starting Remmina when the keyboard layout is set to Maori in the keyboard indicator (indicator-keyboard-service). This happens regardless of XKBLAYOUT="us" in /etc/default/keyboard.

Setting to English (US) while starting Remmina and then back to Maori once it's running seems to work but is a little tedious.

SourceForge.net URL not valid.

Not In Progress as outlined in https://wiki.ubuntu.com/Bugs/Bug%20statuses .

Andre Hugo, et. al., is this still an issue in Vivid via http://cdimage.ubuntu.com/daily-live/current/ (live environment is fine)?

[Bruce Pieterse (octoquad)]

natty and raring are EOL (https://wiki.ubuntu.com/Releases). Additionally, this issue still persists due to https://github.com/FreeRDP/Remmina/issues/365 and http://sourceforge.net/p/remmina/mailman/message/32925292/ which the Remmina project was idle.

Yes, this is still a problem in VV.

[penalvch (penalvch)]

Bruce Pieterse, thanks for the update. Does it still crash in Vivid for you or does the functionality just not work?

[Bruce Pieterse (octoquad)]

Yes steps to reproduce are:

$ sudo apt-get install remmina
$ remmina
Remmina plugin RDP (type=Protocol) registered.
Remmina plugin RDPF (type=File) registered.
Remmina plugin RDPS (type=Preference) registered.
[1] 8135 segmentation fault (core dumped) remmina

Additionally now changing it from XKBLAYOUT="za" to "us" or "mao" also causes a segmentation fault which means the problem has gotten worse since the initial report and the above workarounds no longer work.?field.comment=Yes steps to reproduce are:

$ sudo apt-get install remmina
$ remmina
Remmina plugin RDP (type=Protocol) registered.
Remmina plugin RDPF (type=File) registered.

New valgrind log attached for Vivid which was initially done Graeme Glass (graemeglass) previously.

[Bruce Pieterse (octoquad)]

@Christopher, it seems new maintainers have stepped up: http://sourceforge.net/p/remmina/mailman/message/33228595/
The source code has been moved to Github with more activity as well as a sourceforge.net possibly becoming obsolete for bug tracking in the future.

I have also reported this problem here: https://github.com/FreeRDP/Remmina/issues/441 as I ran into the same problem with just the xfreerdp built from source on 15.04. I can't seem to add the the upstream bug report as launchpad doesn't recognise it.

Thanks

[penalvch (penalvch)]

Bruce Pieterse, thanks for filing upstream. As well, I've already noted the change in website back in December in order to help mitigate any confusion -> https://help.ubuntu.com/community/Remmina .

[Bruce Pieterse (octoquad)]

A fix has been committed (https://github.com/hardening/FreeRDP/commit/27c5b5b22402c3934c6b892bbce5d0e016769390) this should land in 1.2. I have tested with just xfreerdp and the crash no longer occurs with both mao and za layouts.

[Craig (craigvantonder)]

This issue persists, confirmed as occurring in 15.10 with a ZA keyboard layout, switching to US keyboard layout allows it to launch.

[Junaid Loonat (junaid-loonat)]

An alternative fix, which I don't believe has been posted anywhere, is to simply add the following two lines to the remmina preferences file so that the client's current keymap is not used and the 'US' keyboard layout is used instead:

rdp_use_client_keymap=0
rdp_keyboard_layout=409

Hope that helps.

[Joel Wirāmu Pauling (aenertia) (aenertia)]

this occurs when using the Māori keyboard layout also

Appears fixed in remmina-next paa for yakkety https://launchpad.net/~remmina-ppa-team/+archive/ubuntu/remmina-next

[Craig (craigvantonder)]

This issue persists in a fresh install of 16.04.1, Junaids' solution with adding to the Remmina preferences does indeed solve the issue and Remmina will start up.

[Abdul-Rahman Bayong (arbayong)]

This solved the problem for me on Ubuntu 16.10. My remmina worked well from 16.04 and i have always upgraded to the new Ubuntu Release. It even worked well under 16.10 for a month and suddenly i had segmentation faults. My keyboard layout was already 'US'.
Removing the RDP plugin didn't solve the problem. purging and reinstalling remmina and the rdp plugin didn't solve it either. Only the PPA did solve it.

[Bruce Pieterse (octoquad)]

Still an issue in zesty, can the package not be updated? Comment #26 is a good work around.
