[Debian-Islamic-maintainers] Bug#637782: Zekr (1.0.0+repack-5) fails to start - could not detect XULRunner

[Danny Dayus]

Package: Zekr
Version: 1.0.0.0+repack-5

Zekr fails to start, giving the following warning message:

org.eclipse.swt.SWTError: No more handles [Could not detect registered 
XULRunner to use]
     at org.eclipse.swt.SWT.error(SWT.java:4308)

As of 14-8-2021 Zekr.org has a wiki page - 
http://zekr.org/wiki/Trouble_shooting#Failed_to_execute_runnable - which 
mentions a similar problem, and which says that the problem has been 
fixed as of version 0.7.5 by editing 
/home/<username/.zekr/config.properties to change the line

update.enable = true
to
update.enable = false

However, on version 1.0.0+repack-5 the same or similar problem occurs, 
even though the said line in the config.properties file is already 
changed as above by default.

I am using Debian GNU/Linux Wheezy with linux kernel 3.0.1 and XULRunner-6.0
