How odd, it appears to be a quirk of this particular diagram on my
system only. As I said other previously saved diagrams are fine still.
Yes, but some related information is still saved with the file. Found by
just opening the file with an editor and searching for 'nan' (not a number)
and 'inf' (infinite) shows:
<dia:object type="Network - Cloud" version="1" id="O0">
<dia:attribute name="obj_pos">
<dia:point val="1,1"/>
</dia:attribute>
<dia:attribute name="obj_bb">
<dia:rectangle val="-inf,-inf;inf,3.22101"/>
</dia:attribute>
So the cloud object's bounding box gets calculated to really big numbers on
your system. If I save you file on one of my systems the bounding box is
caclculated corrected to:
<dia:object type="Network - Cloud" version="1" id="O0">
<dia:attribute name="obj_pos">
<dia:point val="1,1"/>
</dia:attribute>
<dia:attribute name="obj_bb">
<dia:rectangle val="0.9,0.9;3.1,3.32101"/>
</dia:attribute>
The bounding box get's recalculated after loading the file so the propblem
is not reproduceable, if the miscalculation does not happen at runtime.
The issue might be fixed en passant with
https://bugzilla.gnome.org/show_bug.cgi?id=710818
It is explained to some extend here:
https://git.gnome.org/browse/dia/commit/?h=dia-0-97&id=335ced1909180f0bc4fb064aaa676a86c740dce0
and depends on the C-runtime library used and maybe also the CPU used
