[Libreoffice-qa] Resizing image in Calc nearly freezes whole system?

[Thomas Hackert]

Hello @ll,
we got a report on the de at discuss list, which seems to be 
reproducible on GN/Linux (or better: Debian-based systems). Would 
someone be so kind to test it, please?

Steps to reproduce:
1. download https://media-cdn.ubuntu-de.org/forum/attachments/41/20/8285598-no-border-no-nation.ods
2. open it in Calc
3. click on the image to get the handler
4. drag the right bottom handler to resize it.

On my system (Debian Testing AMD64), this leads nearly immediately 
to a system freeze, where I have to switch to a VT to kill the 
soffice.bin ... :( The problem is, that still after killing the 
process with "kill -9 $PID" will not free the whole RAM / swap / 
whatever, so the system still seems to be blocking somewhere ... :( 
So be warned ... ;)

Tested with:
LO Version: 4.3.7.2
Build-ID: 8a35821d8636a03b8bf4e15b48f59794652c68ba
(no freeze, but I was only able to resize the image at the right 
handler. All others leads to a vanishing image)

Version: 4.4.1.2
Build-ID: 45e2de17089c24a1fa810c8f975a7171ba4cd432
Gebietsschema: de_DE
(same as 4.3.7.2)

Version: 4.4.6.2
Build-ID: 008d5d0ddffba0b82de2a2c36a65b9cba0a6b328
Gebietsschema: de_DE.UTF-8
(freeze)

Version: 5.0.0.5
Build-ID: 437e4abdf9e72fd0a6e6f8697a0e659bc77f9b10
Gebietsschema: de-DE (de_DE.UTF-8)
(freeze)

These are the versions, which I have installed parallel (following 
the instructions from 
https://wiki.documentfoundation.org/Installing_in_parallel/Linux)

Additionally, I tested it with Debian's own version
Version: 5.1.3.2
Build-ID: 1:5.1.3-1
CPU-Threads: 4; BS-Version: Linux 4.5; UI-Render: Standard; 
Gebietsschema: de-DE (de_DE.UTF-8)
, which also nearly freezes the whole system ... :(

I then tried to get a backtrace or even a strace, but alas to no 
avail ... :( IMHO this freezes the system much harder than without 
them ... :(

Is this reproducible on an other system to anyone? And: are you able 
to get a strace / backtrace? Is this already reported to bugzilla?
TIA for testing
Thomas.
