Thanks for the bug report. How do you actually enter an svn+ssh URL in the location bar? If I try this (URL starts with svn+ssh://), I get an error message "Invalid protocol".

It would be interesting to know where in the code it hangs. Could you this:

1. Close all Dolphin windows
2. Run Dolphin with "gdb --args dolphin --nofork"
3. Enter "run" in gdb
4. Reproduce the bug
5. Press Control+Z in the gdb window
6. Enter "bt" and paste the backtrace here

Thanks.

it seems that kdesvn is handling the svn+ssh URL.  this is now with KDE 4.6.1, Dolphin 1.6.1, and kdesvn 1.5.4.

kdesvn generates a lot of unnecessary messages in the notification area while i type the URL:

  * after i type "svn+ssh://":
    * "To better debug SSH connection problems, remove the -q option from 'ssh' in the [tunnels] section of your Subversion configuration file", even though i removed the "-q" from /etc/subversion/config long ago
    * "Unknown host ''"
  * every time i add a path separator until i've entered a Subversion repository path:
    * "No repository found in 'svn+ssh://{path}'"

the first two messages seem to be inconsistent and mutually exclusive--sometimes one will display, sometimes the other, and sometimes neither; usually it's the first.  the third message is displayed every time as described.

when i finally enter a path to a Subversion folder in some repository, i can view and browse the contents with no apparent problem.  i perform kdesvn actions such as viewing Subversion logs, but they don't work:

  * attempting to view the log on a directory causes a progress bar to appear in the notification area that says "no running jobs", and it seems to hang there until i cancel it.  sometimes the job has no text if i expand the notification area, but sometimes it has text like:
      Source: svn+ssh://{path to the queried directory}
      Destination: /var/tmp/kdecache-...{some numbers}.0.{dirname}
  * attempting to view the log on a file triggers two successive warning dialogs named "SVN Error - kdesvn" with the text:
      Unable to open an ra_local session to URL
      Unable to open repository 'file:///var/tmp/kdecache-{username}/krun/{some numbers}.0.{filename}'
    followed by a dialog window named "kdesvn" with what appears to be an empty text area and two buttons, "OK" and "Cancel".  both buttons simply close the dialog.

in both situations, i can still operate Dolphin while kdesvn is misbehaving.

finally, returning to the original issue in this report, if i drag the location icon from the location bar to Places, i get similar behavior in the notification area as when i attempt to view the log on a directory, but Dolphin also hangs as in this bug's description.  canceling the empty job in the notification area works, but Dolphin remains hung until i kill it.


for what it's worth, here's my opinion of things that should be handled better here:

  * kdesvn actions should actually work from Dolphin.
  * even if kdesvn actions don't work from Dolphin, the small form of the notification area should display some text instead of "no running jobs".
  * even if kdesvn actions don't work from Dolphin, the large form of the notification area should always (instead of sometimes) display the source and destination files.  even better, it should indicate that the job is a kdesvn job.
  * even if kdesvn actions don't work from Dolphin, they should fail similarly, whether the target object is a directory or a file, instead of showing strange jobs for one and strange dialogs for the other.
  * even if kdesvn actions don't work from Dolphin, Dolphin shouldn't hang after dropping a location icon to Places.

i'm willing to split this into multiple bug reports if that's appropriate.  let me know which issues should be separated out, if any.


[slightly off-topic] by the way, i heard that Dolphin now has integrated Subversion browsing support.  how do i use it?  must i remove kdesvn?  does it support svn+ssh?


the backtrace from the hung Dolphin instance follows below.  i'm not sure how to get a backtrace of the notification area jobs or from the kdesvn dialogs, if they're relevant.  i'll happily provide them if someone instructs me.

Resetting assignee to default as per bug #305719

Thanks for the info and sorry for the extremely late reply. There is just too much mail coming from bugs.kde.org.

The code where it froze is not executed any more in Dolphin at all, so this bug should not happen any more.

I cannot comment on the kdesvn questions because I'm not familiar at all with it.

(In reply to comment #2)

You must install the SVN plugin and enable it in the "Services" section of the settings dialog.

> must i remove kdesvn? 

I think not.

> does it support svn+ssh?

I don't know. I neither work on nor use the SVN plugin.
