[pkg-wine-party] Bug#845334: wine32: breaks xdg-open, which wants to start wine and crashes

Perhaps because you have Firefox as your default browser?

Well, this depends on alternatives. In any case, I don't want wine
to be run (in particular I have never run a web browser under wine,
so that there is no reason to start doing that here; note also that
I haven't even ever run any desktop application under wine, just
command-line test programs to test MPFR).

Probably because you chose Firefox as the default browser.

I don't know where this comes from. FYI, I also have firefox-esr
installed, and even:

/etc/alternatives/x-www-browser -> /usr/bin/firefox-esr

I suspect a precedence list somewhere in the user's home.
Something like that.

This comes from:

Note: I installed wine32 on 2016-01-07. I don't know what's specific
about 2016-05-22 (except that I had run MPFR tests under wine, but
this wasn't the first time); there was an upgrade to wine32 1.8.1-2
on 2016-05-17.

.local/share/applications/mimeinfo.cache contains:

[MIME Cache]
application/rtf=wine-extension-rtf.desktop;
application/vnd.ms-htmlhelp=wine-extension-chm.desktop;
application/winhlp=wine-extension-hlp.desktop;
application/x-mswinurl=wine-extension-url.desktop;
application/x-mswrite=wine-extension-wri.desktop;
application/x-wine-extension-ini=wine-extension-ini.desktop;
application/x-wine-extension-msp=wine-extension-msp.desktop;
application/x-wine-extension-vbs=wine-extension-vbs.desktop;
application/xml=wine-extension-xml.desktop;
image/gif=wine-extension-gif.desktop;
image/jpeg=wine-extension-jfif.desktop;wine-extension-jpe.desktop;
image/png=wine-extension-png.desktop;
text/html=wine-extension-htm.desktop;
text/plain=wine-extension-txt.desktop;

So, the important line here is:

text/html=wine-extension-htm.desktop;

I don't have any text/html line in the mimeapps.list file.

Before the change:

cventin:~> xdg-mime query default text/html
wine-extension-htm.desktop

After removing the above text/html line:

cventin:~> xdg-mime query default text/html
firefox-esr.desktop

If I delete the ~/.wine directory, I still get firefox-esr.desktop,
and ditto if I remove the wine-related "config" files first: these
buggy config files do not reappear.

No desktop environment, just fvwm, since 1995 (well, at that time,
not on this machine :). Perhaps GNOME was initially run on the
machine just after I installed it, but that's all.

As I can't reproduce the bug with the above change for now, this may
be an obsolete bug, though I couldn't find anything in the ChangeLog
except:

wine (1.6.1-8) unstable; urgency=medium

  * Don't register mime types (closes: #327262).
