Zekr Quran study tool loads and then promptly crashes

Thank you for taking the time to report this bug and helping to make Ubuntu better. This bug did not have a package associated with it, which is important for ensuring that it gets looked at by the proper developers. You can learn more about finding the right package at https://wiki.ubuntu.com/Bugs/FindRightPackage. I have classified this bug as a bug in zekr.

When reporting bugs in the future please use apport, either via the appropriate application's "Help -> Report a Problem" menu or using 'ubuntu-bug' and the name of the package affected. You can learn more about this functionality at https://wiki.ubuntu.com/ReportingBugs.

Abdul Qadeer,

Thank you for reporting the bug.
It seems that package zekr for karmic is broken. I think this is because a dependency package, velocity, has been upgraded to a newer version which is not compatible with zekr0.5.

Abdul Qadeer, for the time being you can use zekr's repository:
http://zekr.org/wiki/Installation#Zekr_Repository

We will try to get it fixed.

installation from download center didnt work so i tried different approaches. after trying solution delivered on zekr help page (which was to use repositories, add them manually and get the packages that way....) application worked nice...

it might be a little hacky but it certainly seems to work on 0.5.1.dfsg-1.1ubuntu1. sadly i've no idea how to debdiff a patch for a jar file (dist/zeka-src.jar)

it seems the net.sf.zekr.engine.theme.TemplateEngine constructor catches the
exception,
Error using VM library : VM_global_library.vm
meaning that context is never initialised. but since the exceptions been handled by catch zekr carries on. better to initialise context no matter what here? this is a
slightly better hacky fix than previously

seems like theres a few ways to sanely ensure context is initialised but i've uploaded the constructor version to the ppa below if anyone wants to try it

https://launchpad.net/~sevenmachines/+archive/release+1/+packages

zekr (0.5.1.dfsg-1.1ubuntu2~sevenmachines1) lucid; urgency=low

  * dist/zekr-src.jar:
    - fix net/sf/zekr/engine/template/TemplateEngine.java contructor
    to initialise context even if theres an exception (LP: #491906)

also from https://bugs.launchpad.net/ubuntu/+source/zekr/+bug/491457
although zekr should handle the exception gracefully it should probably avoid it anyway by not setting velocimacro in res/config/lib/velocity.properties
i've also added this to the ppa for testing

https://launchpad.net/~sevenmachines/+archive/release+1/+packages

zekr (0.5.1.dfsg-1.1ubuntu2~sevenmachines3) lucid; urgency=low

  * debian/patches/05-unset-velocitymacro-library.dpatch:
    - dont set velocitymacro.library resource to avoid an exception on
    velocity init (LP: #491457)

This is fixed in 0.7.5beta3 (which hopefully would enter Debian soon).

I provided a quick fix at the time the bug was reported, but no one put it here yet. The bug is result of a backward incompatibility issue at velocity side. When you upgrade to 1.6.x, older velocity.properties is no longer valid and causes this problem. The simple solution is to replace <zekr>/res/config/lib/velocity.properties with the attached one.

Mohsen

great, this should then get fixed soon with a sync to debian 0.7.5beta3. thanks
