kcmwineconfig doesn't load if Z: drive is removed

[Xwang]

On my Kubuntu 8.04.1, I've noticed that kcmwineconfig (System settings>Advanced>Windows Applications) does not load if a .wine directory is already present. So it is impossible to modify wine settings using this integrated tool. It is necessary to use the winecfg utility. If I remove the .wine directory and start kcmwineconfig, I can setup wine, but then when I close kcontrol and open it back again, it can't load it.
Starting kcontrol from the console and selecting the Windows Applications tool when a .wine directory is already present, it is not opened and in the console the following messages appear:

Pythonize constructor -- pid = 12441
Python interpreter initialized!

Pythonize constructor -- pid = 12441
Warning: could not find DOS drive for current working directory '/home/andreak', starting in the Windows directory.
Traceback (most recent call last):
  File "<string>", line 8, in kcontrol_bridge_create_wineconfig

    self.generalpage = GeneralPage(tabcontrol,self.compact_mode)

    self.reset()
  File "/var/lib/python-support/python2.5/wineconfig.py", line 2908, in reset
    settings = wineread.GetGeneralWineSettings(application)
  File "/var/lib/python-support/python2.5/wineread.py", line 303, in GetGeneralWineSettings
    return GetKeyValues("HKEY_CURRENT_USER\\Software\\Wine")
  File "/var/lib/python-support/python2.5/wineread.py", line 191, in GetKeyValues
    file=open('.registrykey.reg')
IOError: [Errno 2] Nessun file o directory: '.registrykey.reg'
error: *** runFunction failure
;

Ideally it should be possible to use both this integrated tool and the wineconfig one without having such issues.
Do you agree?

PS I don't know if "System settings>Advanced>Windows Applications" is the correct one, I have obatined it by traslating the Italian one "Impostazioni di sistema > Advanced > Applicazioni Windows"

Thanks for your bug report; we'll need some furter info from you.

Please specify what versions of guidance-backends and kde-guidance you are running?

What happens if you run the following command in a terminal?:
"wine regedit /E .registrykey.reg HKEY_CURRENT_USER\\\\Software\\\\Wine"

[Xwang (xwang1976)]

Ok, I'll post the commands and the results obtained so you will have all the info:

Try to run the wine explorer "wine explorer.exe" ... which drive letter and folder does explorer open in and does drive "Z:" exist?

[Xwang (xwang1976)]

Explorer opens in C: and drive z: does not exit because I've removed all drives except for c: (maybe in the future I will add a drive for the cdrom).
Xwang

[Andreas Wenning (andreas-wenning)]

The Z: drive is an alias for your complete unix system; if you add the Z: drive again it should fix your problem. wineconfig does not work without Z: drive as it is now.

[Xwang (xwang1976)]

Ok, adding the Z. drive it works.
I removed it because I was searching for a method to avoid windows application to see files outside the .wine directory.
Is it possible to limit wine using a sort of chroot (so that applications see .wine as the /directory)?
Xwang

[Xwang (xwang1976)]

I've discovered that removing all drives except c: (namely not mapping /, /home/user and so on), I can look at all the directories from a windows application but I can open and write only in directories inside c:. So, since this is, IMHO, a much more safer configuration, I suggest to modify kcmwineconfig so that it is not needed the presence of the z: drive which maps / (giving to windows applications the ability to read and write to all the file the user has access on the pc.

[Andreas Wenning (andreas-wenning)]

@Xwang
After looking into it, it will take some heavy restructuring to make it work without having the Z: drive defined. As the Z: drive is default to have this is probably not critical enough (especially not compared to the restructuring needed) to deserve an SRU (fix in hardy).

Wineconfig is not guaranteed to live in hardy+1 and might be replaced by some other configuration mechanism; I'll keep this bug open to be used in the case that wineconfig does live on.

Kubuntu 8.04 has reached the end of its supported life, and unfortunately the Guidance user configuration tool and the Guidance Power Manager were the only Guidance apps to survive. The rest were removed from distribution and will not be receiving any more bugfixes. Thanks for understanding, and have a nice day.
