[Python-apps-team] Bug#611509: hg view: "pickaxe" action produces 'Error: window name "error" already exists in parent'

[Jonathan Nieder]

Package: mercurial
Version: 1.7.3-1
Tags: upstream

After adding "[extensions] hgk =" to ~/.hgrc, a nice "hg view" command
is available.  But the program does not seem to completely realize it
is hgk:

 - In the "About" menu, the only item is "About gitk".  Shouldn't it
   describe hgk there, too?

 - If I choose the "All Fields" dropdown from the central panel and
   change it to "Pickaxe" and make a search, a dialog pops up:

	Error: window name "error" already exists in parent

   Clicking "Details >>" gives

	window name "error" already exists in parent
	window name "error" already exists in parent
	    while executing
	"toplevel $w"
	    (procedure "error_popup" line 3)
	    invoked from within
	"error_popup "Can't parse git-diff-tree output: $line""
	    (procedure "readfindproc" line 16)
	    invoked from within
	"readfindproc"

   Dismissing the dialog gives

	Can't parse git-diff-tree output :100644
	100644 8295d144ab98 39bed83928a4
	M	rev-parse.c	revparse.
	c

Presumably the error message should refer to the mercurial command
actually used and the "Pickaxe" action should be suppressed?
