Solving Zekr Problem in Ubuntu 11.10 Oneiric Ocelot

An upgrading Ubuntu from 11.04 Natty to 11.10 Oneiric Ocelot remains a problem on Zekr launching. Zekr is Quranic study tool, it is available in www.zekr.org. When I update my Ubuntu 11.04 to 11.10, I got the following problem;

        at org.eclipse.swt.SWT.error(SWT.java:4308)
        at org.eclipse.swt.browser.Mozilla.create(Mozilla.java:683)
        at org.eclipse.swt.browser.Browser.(Browser.java:96)
        at net.sf.zekr.ui.QuranForm.makeFrame(QuranForm.java:475)
        at net.sf.zekr.ui.QuranForm.init(QuranForm.java:300)
        at net.sf.zekr.ui.QuranForm.(QuranForm.java:278)
        at net.sf.zekr.ZekrMain.startZekr(ZekrMain.java:51)
        at net.sf.zekr.ZekrMain.main(ZekrMain.java:91) 

Then, I search how to solve this problem and find a solution of this problem. The problem can be solved by editing file ~/.zekr/config/config.properties.

Just type in the terminal

sudo nano ~/.zekr/config/config.properties

and find the following,

options.browser.useMozilla = true

Then, change to:

options.browser.useMozilla = false

Let's try, it works for me!
