The virtual desktop method is good as well, I agree.  Thanks for mentioning

Yes, Xavier, it's the right priority.  Any input to LilyPond which makes  
the program crash is critical.

http://code.google.com/p/lilypond/issues/detail?id=1385

Your `alternating between them in separate tabs' is called `blink  
comparison' in astronomy.  It's one of my favourite methods in finding  
smallest differences (as sometimes needed in testing rendering improvements  
in FreeType) since even sligthest changes pop up quite easily.  On my  
GNU/Linux box using KDE, I've set up a bunch of virtual desktops, and I've  
assigned key combinations to easily switch between them; in other words,  
I'm not limited to a browser while doing blink comparisons, any image  
viewer will do.

setting 'staff-space to 0.0

http://code.google.com/p/lilypond/issues/detail?id=1382

Xavier: Critical, because we ought to have error checking to prevent  
segfaults.


Patrick: It seems like we ought to spit out a warning message and tell the  
user we're setting the staff-space to whatever value we are setting it to.
And perhaps instead of 1, we ought to set it to 0.1 or 0.01 or something  
like that; if the user sets it to 0 they may really want a small value  
(although why, I'm not sure).

Hi!

This feature has been asked again by a user on the French user mailing
list.  Actually Wilbert's code seems to work really fine.

Could a wise developer review it and then push it so it will be
implemented directly into LilyPond?

Many thanks to Wilbert again !

Sorry if I was too brief or unintentionally mysterious, Patrick.  I certainly 
don't want to slow you down.

I would have suggested medium priority because it has not been seen 'in the 
wild', and only happens in the first line of a score, but I imagine it could 
easily occur in real music.


I agree with you in that this is a different issue than 1290, so I'll
add it to the tracker (with a different example snippet).

http://code.google.com/p/lilypond/issues/detail?id=1385

I can't test to see if it's a regression right now, but I assume that it is.



I confirmed, using your example, that it is a regression relative to 2.12.3

Are you compiling LilyPond from scratch and using Guile 1.9, by chance?

The reason I ask is because I have seen these  errors
many times with my testing of Guile 1.9 with LilyPond.

If you're using Guile 1.8, I'll have a look at this again, since I
can't reproduce with Guile 1.8 and latest LilyPond git.

I have a created a new snippet for this report that likely demonstrates the

3\mm, and 4\mm respectively.

g,1
\repeat unfold 2 { g4 g g g }
g'''4 ~ g'''4 g'4 ~ g'4
  }
  \layout {
% Uncomment each of these in turn to see the spacing changes
 indent = 1 \mm
% indent = 2 \mm
% indent = 3 \mm
% indent = 4 \mm
short-indent = 1 \mm
