SVG File Crashes on Startup

[Will Haines]

The following SVG file, created with inkscape .46, crashes the system when I attempt to open it.

Upon attempting to open the SVG:

Microsoft Visual C++ Runtime Library

Runtime Error!
Program: C:\Program Files\Inkscape\Inkscape.exe

This application has requested the Runtime to terminate in an unusual way.
Please contact the application's support team for more information

Then,

Inkscape encountered an internal error and will close now.

The error is 100% reproducable on Windows XP SP3. I've also attempted to open it on OSX 10.6. I attempted to get a backtrace using the Inkscape20168-0811101920-fulldbg upload, with the following result:

crash confirmed on Win32 build 20418 from Dec 30, exit message is :

ERROR:src/libnrtype/Layout-TNG-Compute.cpp:1348:bool Inkscape::Text::Layout::Calculator::calculate(): assertion failed: (_flow._input_stream.front()->Type() ==TEXT_SOURCE)

Emergency save activated!

[Alvin Penner (apenner)]

the file EditorBroken.svg has been separated into two pieces. The first piece will load properly into Win32 build 20418

[Alvin Penner (apenner)]

the second piece causes the above crash

[Alvin Penner (apenner)]

the crash appears to be caused by a <flowSpan> element that had a null value where it was expecting text :

if I take the element :
<flowSpan id="flowSpan10489" style="font-weight:normal;-inkscape-font-specification:Gill Sans MT"></flowSpan>

and replace it with :
<flowSpan id="flowSpan10489" style="font-weight:normal;-inkscape-font-specification:Gill Sans MT">T</flowSpan>

then the crash disappears, file attached.

I commited a fix in revision 20611, pls. double-check and report, Adib.

[Alvin Penner (apenner)]

running Win32 rev 20635, I get a warning as below, but no crash, file loads perfectly.

** (inkscape.exe:3048): WARNING **: flow text is not of type TEXT_SOURCE. Abort.

Thanks, theAdib !
