Inkscape 0.48.1 : "perspective" problem

[nigrone]

OS = Windows XP (SP3)
Inkscape 0.4811

[nigrone (nigrone-marie)]

Sorry ...for above ...
Here is a description of the problem :
I am trying to use the "Extensions/modifierchemin/perspective" feature on Inkscape 0.48.1.
But , on my computer (Windows XP SP3) I keep getting the following crash message :

"Application défaillante pythonw.exe, version 0.0.0.0,
 module défaillant lapack_lite.pyd, version 0.0.0.0,
adresse de défaillance 0x00089440."

I tried to install Inskape on :D instead of C: (as usualy done ...) I also tried the "Portable" version of inkscape ...but I get the same crash in all cases.

The fact that bother me is that I do not get the problem on an other PC , also running "Windows XP SP3".

I did a full test of my Hardware memory (in case ...) but 0 error d was detected.

PS : attached the sample file used to test the "Perspective" feature

Would you have any Idea of what the Problem could come from ????
In advannce many thanks for your help

- do you have Python installed separately from Inkscape on either of these machines?

- could you compare the size and date of the file lapack_lite on these two machines?

- in my case, Windows XP, Inkscape 0.48.1, this file has the properties:

 Directory of D:\Program Files\Inkscape\python\Lib\site-packages\numpy\linalg

05/29/2010 03:41 PM 2,382,875 lapack_lite.pyd

Not reproduced on Windows XP, Inkscape trunk revision 10145.
Tested with the default numpy version (1.4.1) and also tried a more recent version (1.5.1). No error message.

I did some "research about the co-existence of several "pyton*.exe" on the PC exhibiting the problem.
and I got :
========================================================
python.exe : C:\Program Files\LibreOffice 3\program
                          taille = 12288 ocyets
---------------------------------------
python.exe: C:\Program Files\LibreOffice 3\Basis\program\python-core-2.6.1\bin
                         taille = 27136 octets
========================================================
python.exe : D:\Program Files\Inkscape\python
                         taille = 26624 octets
========================================================
pythonw.exe : D:\Program Files\Inkscape\python
                           taille = 27136 octets
========================================================
lapack_lite.pyd: D:\Program Files\Inkscape\python\Lib\site-packages\numpy\linalg
                          taille = 2 382 875 octets
========================================================
As you can see, I have 2 additional "pyton.exe" installed by "libreOffice" , but on the "C:" partition ,

while the "python*.exe" as well as "lapack_lite.pyd" (installed for "Inkscape package"), are
 on the "D:" partition.

I also find out that, on the 2nd PC (where "perspective extension" does not exhibit the problem....)
I only have a single occurence of "Python*.exe" files ( in the "inkscape" program directory)

This situation , seems to confirm that there is some kind of interference between the different "python*.exe" files, eventhough they are on 2 different partitions .....

I will temporarily rename the ones installed by "LibreOffice", to see if it solve the problem...and I will let you know.

Thanks anyway for your assistance.

@nigrone - Did you manage to make the extension work by renaming the LibreOffice Python files? We have some other reports with potential issues with coexisting Python installations, but as far as I can tell, they are all unconfirmed.

Since the underlying issue is the same, I'm grouping both reports in Bug #896659.
