Libreoffice crash when typing some Malayalam text using ibus

[Björn Michaelsen]

see upstream

[balakrishanan (a-p-balakrishan)]

When i try to type in Libreoffice writer in my language the key combination comes with "a&x" application crash and exits.

[Jmadero-dev (jmadero-dev)]

This is not enough information for us to properly triage the bug.

1. What language?

2. What distro?

3. What version of LibO

That's the minimum we need. Marking as NEEDINFO, please provide the information and reopen as UNCONFIRMED. I was unable to reproduce this using Telugu language + iBus + Bodhi Linux + LibO Version 3.6.2.1

[balakrishanan (a-p-balakrishan)]

I tryed Liberoffice 3.4,3.5,3.6.1

Ubuntu 11.10,12.04

Basic language English India

Problem in typing Indian language Malayalam.

Input method IBUS

balakrishanan: could you try to retrieve a backtrace (see https://wiki.documentfoundation.org/BugReport#How_to_get_a_backtrace_.28on_Linux.29)? It could be very useful for debugging.

I am retrieve a backtrace of Libreoffice with this

[julien2412 (serval2412-6)]

balakrishanan: you retrieved an strace, it may be useful but it's not a stacktrace/backtrace.

Could you follow this link? https://wiki.documentfoundation.org/BugReport#How_to_get_a_backtrace_on_Linux

 pls find this new one

[julien2412 (serval2412-6)]

balakrishanan: thank you for the bt!
Would it be possible you attach the font (ttf file I think) to the bugtracker so we can try to reproduce the problem?

[balakrishanan (a-p-balakrishan)]

font attached

The font is default in ibus package . i am attaching font here too
For enable Malayalam package i add ibus-m17n with synaptic.
or sudo apt-get install ibus-m17n
in ibus preference i select's Malayalam

i am using two Input Methods mozhi and in-script both having same problem
to reproduce problem

if you using Mozhi you can type hOm with space 'O' must be capital.

in in-script you can type the word uax for this. ax combinations having problem.

Thank you

[julien2412 (serval2412-6)]

balakrishanan: thank you for your feedback and for having attached the fonts.
About both input methods, I don't know how to do this.
I put a core dev on cc, he might help here.
I put the tracker to New since I don't have more question and you provided a backtrace.

Caolán: one for you? (a bt with symbols has been attached by the reporter)

hmm, a crash in icu itself apparently

[Caolanm (caolanm)]

So, I can fix our *internal* icu to not crash here, but the icu you are using is your system icu from Ubuntu, so that needs to be fixed for it not to crash for you.

Perhaps Björn can help with that, and added some other distro folk who might want to patch their own icus too (I'll do Fedora)

I don't seem to have the right keyboard for this, can someone attach the resultant document, or the exact Unicode chars? ICU has a short time to get this patch in (i.e. today).

Steven R. Loomis

i am attached the file contain character's typed in meera font.

 i am using qwert keyboard.

[Caolanm (caolanm)]

This is surprisingly difficult to reproduce with a static example. But here's a surefire way to crash for me with raw unicode input
0xd39, 0xd4b 0x0d02
(in gtk, ctrl+shift+u d39 space ctrl+shift+u d4b space ctrl+shift+u d02 space -> crash)

[Björn Michaelsen (bjoern-michaelsen)]

needs to be fixed in icu -> invalid for libreoffice packaging.

[Launchpad Janitor (janitor)]

This bug was fixed in the package icu - 4.8.1.1-10ubuntu1

---------------
icu (4.8.1.1-10ubuntu1) raring; urgency=low

  * Fix crash on rendering incremental Malayalam text input (LP: #1130284).
