[Pkg-dia-team] Bug#788727: dia: "Standard - Arc" with negative/zero curve_distance forcibly changed into "Standard - Arc" with 0.01 curve_distance

[AYANOKOUZI, Ryuunosuke]

Package: dia
Version: 0.97.3-1
Severity: normal

Dear all,

For "Standard - Arc" with negative curve_distance,
the shape of the object is curved arrow on oldstable,
while it is straight arrow on stable.
The shape should be like a curved arrow on both versions.
This seems to be a regression.

I opened the dia file[1] and took screen-shots on oldstable[2] and stable[3].
Please check them.

[3] Standard_-_Arc_curve_distance_sc_debian8.1_dia0.97.3-1.png

On stable, after saving the dia file,
the value of curve_distance is changed into 0.01.

$ dia -e Standard_-_Arc_curve_distance_sc_debian8.1_dia0.97.3-1.dia -t dia Standard_-_Arc_curve_distance.dia
