Can't open except from launcher which results in several active instances

[Bob Merhebi]

1) $ lsb_release -rd
Description: Ubuntu 12.04 LTS
Release: 12.04

2) $ apt-cache policy minbar
minbar:
  Installed: 0.2.1-7
  Candidate: 0.2.1-7
  Version table:
 *** 0.2.1-7 0
        500 http://ubuntu-archive.mirrors.proxad.net/ubuntu/ precise/universe amd64 Packages
        100 /var/lib/dpkg/status

3/4) I can't seem to find a way to bring minbar back (after 'closing') from the background. The only way is to use the launcher (which opens a new instance). This becomes apparent when the athan is played; several athans interefer as they play together!

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

I tested Minbar with Ubuntu 12.04, 12.10, 13.04, and 13.10. Minbar still disappears from the Unity top Bar. Do you know if this will be fixed in Ubuntu 14.04? I hope that it can be fixed in the LTS because our users require Unity along with Minbar.

Thank you so much!

Very long time with no update regarding this. The application is still not shoing on icon tray (near clock) while others like owncloud or redshift are working fine.
I tried in every Ubuntu release since years. Now I am with 15.04.
This way the application is unusable and there is no other option I found on GNU/Linux.
Thanks in advance.
