SVG file blocking inkscape (huge memory allocation, cpu overload)

[Ivo Blöchliger]

When working with inkscape, it crashed. When opening the last saved file (attached to this report) this causes Inkscape to freeze, on the latest downloadable Windows Version (as of July 3 2013) as well as with Ubuntu Linux, Inkscape version (Inkscape 0.48.3.1 r9886 (Jan 29 2013)). The file displays fine in Firefox, except for the 5-stars in the right side of the image, they are distorted. When opening the file with Linux, the following message is repeatedly displayed:

** (inkscape:7070): WARNING **: GC Warning: Repeated allocation of very large block (appr. size 1167360):
        May lead to memory leak and poor performance.

Hard to tell, whether this could be a security problem, but it is conceivable that memory corruption occurs.

I hope this helps improving this wonderful program even more.
Many thanks to all the developers!

That specific group of paths had a LPE applied - try the attached version with the path effect removed (by manually editing the file):

$ diff 1197692-line-follower-avec-portes-artistique.svg 1197692-line-follower-avec-portes-artistique\ copy.svg
1498,1499c1498
< transform="matrix(0.18318451,1.0123207,-1.0123207,0.18318451,7648.2029,-622.53019)"
< inkscape:path-effect="#path-effect14941">
---
> transform="matrix(0.18318451,1.0123207,-1.0123207,0.18318451,7648.2029,-622.53019)" >

The path effect itself:

    <inkscape:path-effect
       effect="skeletal"
       id="path-effect14941"
       is_visible="true"
       pattern="#use7534"
       copytype="repeated"
       prop_scale="1"
       scale_y_rel="false"
       spacing="0"
       normal_offset="0"
       tang_offset="0"
       prop_units="false"
       vertical_pattern="false"
       fuse_tolerance="0" />

The referenced pattern object of the path effect "Pattern along Path" is inside the group to which the path effect is applied (id "use7534").
