collision of the dot of a dotted rest and accidental

[violist]

Hi!

I reported the collision of the dot of a dotted rest and accidental as a 
bug already.

But what can I do meanwhile? I would like to push the note together with 
its accidental a bit to the right (and everything following, of course). 
But how?

I don't want to make more space generally with one of those:
  \override SpacingSpanner  #'base-shortest-duration = #(ly:make-moment 
1 8)
   \override SpacingSpanner  #'spacing-increment = #1.2
   \override SpacingSpanner  #'shortest-duration-space = #2.5
because I like the notes generally rather narrow, to get enough bars in 
one line.

I read the Subject: "horizontal shift of note column not working" from

but I did not find what helps to me.

Can someone help? Thanks!!!
