The attached SVGs crash DeerParks SVG. It seems to be related to the speed of
the pc / mac and the size of the SVG. i.e. 2.4Meg P4 XP Pro Pentium PC will cope
with verysmallGraph.SVG and smallGraph.SVG, 1.25Meg Mac v10.2 PowerBook G4 will
cope with smallGraph.SVG, 800Meg Mac v10.1.5 G4 won't even start!? Note: it
doesn't appear to be memory as 800Meg G4 has most.
IE and Adobe SVG will do all graphs and much, much bigger ones.

Reproducible: Always

Steps to Reproduce:
1. Try and display the attached graphs

Actual Results:  
'Expectectedly quit'

Expected Results:  
Displayed a temperature line graph, clicking on graph allows navigation.

I only get a hang not a crash, reporter if possible can you list some talkback
ids please.

Comment 6

[Paul Hopgood]

I need some help on the talkback id. I don't think the nightly build has
talkback in (or I don't understand how to use it) and I have no way to build
DeerPark. Can some one tell me where I can get a talkback build (Windows XP is
most convenient)? .
I've been trying to track down if it's just some particullar aspect of the svg
(the path, the clipping e.t.c.) but it could be any part of the whole as there
even appears to be a difference between commenting out lots of code and actually
removing it!?

the very small graph was filling my screen with about 4 oversized letters, 'ple'
or something like that, may have been part of 'complex'
I wanted to add a screenshot, but now can´t access svg.
Default entry for svg in Windows registry is the inkscape editor, and when I try
to open the testcase I get asked to download  or open with default. I tried to
add svg to the extension list, to no avail, but now I can´t open svg from disk.
Next nightly I´ll retest with a fresh profile.

I've track the problem down to a problem with very small scaled down dashed arrays!
I've send a TalkBack id TB6191282E which is the crash from the
'SmallDashArray.svg' that I'll attach in a mo. The offending line is heavilly
commented.

[Paul Hopgood]

Attachment: Small dashed array causes problem.

This appears to be the minimum needed to reproduce the problem.
The heavily commented (very) small dashed array causes the  problem.

rename it from .svg to .xml and you'll be able to open it

No specific bug / patch referenced as the fix.

Sorry if I was wrong to changed it to fixed but I'd just tried my tests with the Mozilla 1.5 Release Candidate and it would have appeared to have been fixed (maybe as a reult of something else!?).

The something else is the use of Cairo, GDIplus.dll isn't needed anymore.
So this bug also could be NOT fixed, as nobody tested a build which doesn't work without GDIplus.dll. You can't test this bug using a build which also works without GDIplus.dll.
A bug is resolved fixed only when it is known which checkin fixed it, here you are testing a workaround, you don't know if it got fixed. So somebody looking here to get the last build using GDI doesn't know where to get it, or if it is working.

No GDIplus.dll, tested working on http://www.croczilla.com/svg/samples/
tested not crashing on testcases here.
