something got broken in 1.1.1 ,

when doing bridges , slic3r puts way too much flow and bridges sag and fall down.
bridge flow ratio setting give no effect at all (is ignored)

1.0.1 works fine.

here are gcodes generated by both slic3rs :
http://83.15.83.106/tmp/slic3r/przegub2.gcode - experimental version
http://83.15.83.106/tmp/slic3r/przegub3.gcode - 1.0.1 stable

I just tried, and bridge flow ratio has a visible effect on the output.
What's the evidence showing this bug reappeared?

@alexrj alexrj modified the milestone: 1.1.4, 1.1.3 May 28, 2014

yeah, tested bit harder and it seems it's tweakable, just the flowrate itself changed significantly vs 1.0.1 so i got fooled . sorry for wasting your time.

tried again with testcase :

and unfortunatelly bug IS there.

results :
1.0.1 : ; filament used = 923.4mm (6.4cm3)
1.1.3 with bridge flow ratio 1 : ; filament used = 1011.4mm (7.0cm3)
1.1.3 with bridge flow ratio 0.5 : ; filament used = 1011.4mm (7.0cm3)

http://83.15.83.106/tmp/slic3r/stable_Bridge_test.gcode (1.0.1)
http://83.15.83.106/tmp/slic3r/Bridge_test.gcode (1.1.3, bridge flow ratio 1)
http://83.15.83.106/tmp/slic3r/Bridge_test_05.gcode (1.1.3 bridge flow ratio 0.5)

Oh, ugly regression. Bridge flow was incorrect when a default extrusion width was specified (like in your case). I added several regression tests on this now. Thank you for reporting.
