inkscape crashes when trying to open or preview an inkscape .svg file

[Christoph Gillessen]

Mac OS X 10.7.3
XQuarz 2.6.3
inkscape 0.48

When inkscape saved a file that I had worked on for a couple of hours, it crashed producing an additional backup of the current file.
When I try to open either the saved file or the crash backup, inkscape crashes again. This also occurs when the file is to be shown as preview in the open dialogue.

Cheers

on Windows 7, Inkscape 0.48.3.1, the file opens correctly, as far as I can tell.

however, I get the following error messages in the console output

C:\Program Files\Inkscape>inkscape

 int flags) : throw in ((SPObjectClass *) G_OBJECT_GET_CLASS(this))->update(this

Crash reproduced with the official package of Inkscape 0.48.2 for Mac OS X (32bit), running on Mac OS X 10.5.8 and OS X 10.7.3
Crash reproduced with local 32bit builds of Inkscape 0.48.2 on Mac OS X 10.5.8

Crash not reproduced with local 32bit builds of Inkscape 0.48.3.1 and current trunk on Mac OS X 10.5.8
Crash not reproduced with local 64bit builds of Inkscape 0.48.2, Inkscape 0.48.3.1 and current trunk on OS X 10.7.3

Notes:
1) If local 32bit builds do not crash when loading the original file, they display these console warnings:

inkscape-bin(8954,0xacaf32c0) malloc: *** mmap(size=1207959552) failed (error code=12)
*** error: can't allocate region
*** set a breakpoint in malloc_error_break to debug

** (inkscape-bin:8954): WARNING **: SPObject::updateDisplay(SPCtx *ctx, unsigned int flags) : throw in ((SPObjectClass *) G_OBJECT_GET_CLASS(this))->update(this, ctx, flags);

3) Local 64bit builds (stable and trunk) load the original file without console messages.

AFAICT this issue is related to or a duplicate of
Bug #345371 “stroked and scaled Linked Offset text causes a crash upon open file”
<https://bugs.launchpad.net/inkscape/+bug/345371>

Changing the stack order of the layers (moving the one with the original text to the bottom, so that linked offsets referencing the text are rendered after the original) prevents Inkscape 0.48.2 (32bit) from crashing (modified version attached) - this will alter the appearance though.
