new error since upgrade to 2.6 - broken pipe

Dear Forum

Thank-you all for all the help so far in my other post. I've opened a new post because of another error. Seriously, guys; I've tried valiantly to fix this one but I'm so lost... Now, in my reading of all of the other posts I can find, I've learned to attach dmesg output and also to run from the command line and all that, but it's achieved nothing.

When running Stepconf, even from the command line, I get a broken pipe error. Saga ensues:

gareth@cnc-01:~$ stepconf
Xlib: extension "RANDR" missing on display ":1.0".
/usr/bin/stepconf:1220: Warning: g_path_get_dirname: assertion `file_name != NULL' failed
self.xml = gtk.glade.xml_new_from_buffer(doc, len(doc), domain="linuxcnc")
/usr/bin/stepconf:1220: GtkWarning: gdk_pixbuf_new_from_file: assertion `filename != NULL' failed

/usr/bin/stepconf:1220: GtkWarning: GtkSpinButton: setting an adjustment with non-zero page size is deprecated
self.xml = gtk.glade.xml_new_from_buffer(doc, len(doc), domain="linuxcnc")

============= I'm sure those errors are unimportant; I'm running over VNC
============= The following happens when I open the "Test axis" dialog

/usr/bin/stepconf:2225: GtkWarning: GtkSpinButton: setting an adjustment with non-zero page size is deprecated
widgets.testvel.set_range(0, maxvel)
/usr/bin/stepconf:2226: GtkWarning: GtkSpinButton: setting an adjustment with non-zero page size is deprecated

widgets.testamplitude.set_range(0, 1000)
/usr/bin/halrun: option requires an argument -- f

Stepconf encountered an error. The following information may be useful in troubleshooting:

Traceback (most recent call last):
File "/usr/bin/stepconf", line 2035, in on_jogplus_pressed
self.update_axis_params()
File "/usr/bin/stepconf", line 2024, in update_axis_params
halrun.flush()
IOError: [Errno 32] Broken pipe

Incidentally, if I run halrun -U, I get the following:

root@cnc-01:~# halrun -U

RTAPI: Locked memory limit is 64KiB, recommended at least 20480KiB.
This can cause the error 'could not open shared memory'.

Dear All

I never got to the bottom of the broken pipe problem, but I am no longer using Stepconf because my XYUV configuration is not compatible with it. I have now leapt head-first into hand-coding my configs.

Thank-you all!

i'd guess that this is picking up the older version of stepconf rather than the version for 2.6
