crash dialog

Hi,
I already reported bug https://bugs.freedesktop.org/show_bug.cgi?id=85056 but
because of many problems in this bug report I was advised to open a new bug
report.

On my computer there was LibreOffice 4.2.6.2 and I have been using it for like
a month without a single crash incident (previously using previous versions of
LibreOffice also without crashing incidents).

How did problem appear?
1. I have uninstalled LibreOffice 4.2.6.2.
2. Manually deleted installation left overs from C:\Programs\LibreOffice4 (this
is my install dir).
3. Install Libreoffice 4.3.2.2 and now hell has been on fire. LibreOffice
Writer (also similar problem with Calc) is crashing non-stop. I can do several
things but none of them are reproducible.

For example:
a) I type text and Writer crashes - but not all the time.
b) I copy/paste the image from image editor and Writer crashes - but not all
the time.
c) I copy/paste the text and Writer crashes.
d) I clicked on AutoSpellcheck button and Writer crashes.

Each time crash appears I need to go through document recovery process and I
hope I haven't lost too much work (between last save and crash).

All above is just not reproducible!!! Please don't bother if LibreOffice is not
crashing in your case, then you will not be able to reproduce.

I can never say when crash will appear. It is pure hell working like this. Then
at one point when crash appeared and I already have few pages of text and
images and I was not in the state of losing my work and Writer crashed and
after restarting it crash repair started and immediately after repair Writer
crashed again. I repeated this 5 times in a role and I couldn't get Writer up
with my document.

I was stuck... So I reversed back:
1. Uninstall  LibreOffice 4.3.2.2.
2. Manually deleted installation left overs from C:\Programs\LibreOffice4.
3. Install Libreoffice 4.2.6.2 and magically I was now working for two days at
least 5 hours without a single crash.
4. I also opened document and recovery went OK and no crash at all.

It looks to me that there is some regression problem in LibreOffice 4.3.2.2
comparing to 4.2.6.2


Because I have a virtual machine, I have created several snapshots, so I can go
to previous state if required.

Today I did the following:
1. Reverted virtual machine back to my LibreOffice 4.3.2.2 state.
2. Opened Writer.
3. Started WinDbg tool to start debugging process.
4. Just start typing some random keys on keyboard - it were letters keys.
5. And crash appeared. It is so easy to crash. I am attaching bug_report
output.
What I see from bug report is that "Python" has crashed. This is probably
LibreOffice embed Python.

I also investigated and I see embed Python is also used in my outer tools like
Gimp and Komodo Edit:


C:\>dir python.exe /s
 Volume in drive C has no label.
 Volume Serial Number is DCD7-FA64

 Directory of C:\Programs\ActiveStateKomodoEdit8\lib\python

06.06.2013  12:45            27.136 python.exe
               1 File(s)         27.136 bytes

 Directory of C:\Programs\gimp2\Python

15.05.2013  21:43            26.624 python.exe
               1 File(s)         26.624 bytes

 Directory of C:\Programs\LibreOffice4\program

18.09.2014  17:16            19.232 python.exe
               1 File(s)         19.232 bytes

 Directory of C:\Programs\LibreOffice4\program\python-core-3.3.3\bin

18.09.2014  12:19            27.136 python.exe
               1 File(s)         27.136 bytes


Also another point. When crash appears I don't get classical LibreOffice crash
window, but instead getting in my opinion some Windows like component dialog
(or maybe even Python internal dialog, don't know). See attached print-screen.

My humble opinion is this is going to be very hard to reproduce. It looks like
LibreOffice Pyhton collides with some other Python or something like that. So I
suggest one of developer gets into debug trace and if additional info are
required I can always revert back my virtual machine and make additional tests.

Regards
