hi,

this evening after d-u ii wanted to open "gftp" in user-console,

but suddenly: all ended with: error-message:


Attempt to unlock mutex that was not locked
Abgebrochen



is this one of the gnome warnings in upgrade-warnings ? or a other thing ? (32-bit-siduction)

 ähm: my dictionary can't help:

what is the meaning of  "mutex" ?

or:
what is the right translation for: "Attempt to unlock mutex that was not locked"

in german ...

is that blocked from maintainer or is that a user-prob ?

This problem also affects radiotray.  There is a workaround, not a real fix.  See comment #10 on this bug report.

At your "/" with root terminal
Code: [Select]
find . -type f -name SysTray.py
Edit the file SysTray.py, by commenting out line 185. **


** EDIT:  After thinking a bit, probably SysTray.py is not the file that is making the gtk call, in the case of gftp.   But the same
Quote
gtk.gdk.threads_init()
call as SysTray.py makes is probably the cause of your mutex lock error.

"Mutex" is not a real English word, btw -- just a technical term invented for software enginees to describe a "mutual exclusion object" -- see here.

thanx dibl !

i am not alone - puhhh ...

locate systray.py

usr/share/hplip/systray.py
but systray.py ended there ...unfortunaly ...ended with line 146  ...a real comic ...

 no line 185

which is the text in usual line 185 ?                                               



Edit: thanx: but: there is no word like "gtk.gdk.threads_init()"

...i could wait to next incoming debian ,)

In the SysTray.py that was in my radiotray installation, line 185 is

Code: [Select]
gtk.gdk.threads_init()
And you need the capital "S" and capital "T" in the file name!

and the forum text editing is not working for me today.  :(

The other funny thing, but only for me -- gftp launches perfectly here, both from Alt-F2 and from terminal.


The underlying problem is described as a bug in the newest gtk.

Well .... no more -- today gftp is also crashing with the same error.  Time to learn a new skill.  There is a firefox/iceweasel add-on named fireftp that seems to get the job done just as well.  Took me about 15 minutes to get the hang of it.  Go to your ftp URL, log in as needed, and when your remote data are showing, right-click and choose the ftp view. You get the two panels and transfer arrows -- looks and works very familiar.

gftp fails with this error on three different KDE systems.  Tomorrow I'll try it on my LXDE netbook.  As noted above, radiotray runs fine after the workaround is applied.  It is strange how few bug reports on this error are out there -- possibly there is a new package or a recently updated package causing it, so only some sid users are affected so far.  But some of the bug reports you can find for this error with other packages go back in time some years.

Still like my first posting: siduction 32-bit


this day: new d-u, later in terminal as user:

gftp
to ...upload or download : click on "Lesezeichen"  to let it run:

I saw some gtk package updates this morning, so I gave gftp a try, and now it is starting correctly with no errors.
