Bug 512477

Try 'hp-setup --disable-dbus' -- does that work around it?

Oh, wait, that's an hp-toolbox option...

An update of the situation is

1) it works when I run "hp-setup -i"

2) I've run strace and this is the last part of it

futex(0x98c4114, FUTEX_WAIT_PRIVATE, 1, NULL <unfinished ...>

... nothing more is added after that

3) I've used the python debugger and found that it hangs on a call to
QApplication(sys.argv)

> /usr/share/hplip/setup.py(193)<module>()
-> log.debug("param=%s" % param)
(Pdb)
> /usr/share/hplip/setup.py(196)<module>()
-> if mode == GUI_MODE:
(Pdb)
> /usr/share/hplip/setup.py(197)<module>()
-> if ui_toolkit == 'qt3':
(Pdb)
> /usr/share/hplip/setup.py(202)<module>()
-> if not utils.canEnterGUIMode4():
(Pdb)
> /usr/share/hplip/setup.py(206)<module>()
-> if mode == GUI_MODE:
(Pdb)
> /usr/share/hplip/setup.py(207)<module>()
-> if ui_toolkit == 'qt3':
(Pdb)
> /usr/share/hplip/setup.py(280)<module>()
-> try:
(Pdb)

-> from PyQt4.QtGui import QApplication, QMessageBox
(Pdb)
> /usr/share/hplip/setup.py(282)<module>()
-> from ui4.setupdialog import SetupDialog
(Pdb)
 /usr/share/hplip/setup.py(287)<module>()
-> app = QApplication(sys.argv)
(Pdb)

... hangs

4) but, if I run it via the hp-toolbox (Device, Setup device), it always works.

5) on my PS3 it always works

I don't really know who to blame here...

Me either. :-(

This message is a reminder that Fedora 11 is nearing its end of life.
Approximately 30 (thirty) days from now Fedora will stop maintaining
and issuing updates for Fedora 11.  It is Fedora's policy to close all
bug reports from releases that are no longer maintained.  At that time
this bug will be closed as WONTFIX if it remains open with a Fedora 
'version' of '11'.

Package Maintainer: If you wish for this bug to remain open because you
plan to fix it in a currently maintained version, simply change the 'version' 
to a later Fedora version prior to Fedora 11's end of life.

Bug Reporter: Thank you for reporting this issue and we are sorry that 
we may not be able to fix it before Fedora 11 is end of life.  If you 
would still like to see this bug fixed and are able to reproduce it 
against a later version of Fedora please change the 'version' of this 
bug to the applicable version.  If you are unable to change the version, 
please add a comment here and someone will do it for you.

Although we aim to fix as many bugs as possible during every release's 
lifetime, sometimes those efforts are overtaken by events.  Often a 
more recent Fedora release includes newer upstream software that fixes 
bugs or makes them obsolete.

The process we are following is described here: 
http://fedoraproject.org/wiki/BugZappers/HouseKeeping

Fedora 11 changed to end-of-life (EOL) status on 2010-06-25. Fedora 11 is 
no longer maintained, which means that it will not receive any further 
security or bug fix updates. As a result we are closing this bug.

If you can reproduce this bug against a currently maintained version of 
Fedora please feel free to reopen this bug against that version.

Thank you for reporting this bug and we are sorry it could not be fixed.
