Bug ID: 404794
Summary: Gwenview crashes when opening a very specific picture
Product: gwenview
Version: 18.12.2
Platform: Compiled Sources
OS: Linux
Status: REPORTED
Severity: crash
Priority: NOR
Component: general
Assignee: gwenview-bugs-n...@kde.org
Reporter: acc12345...@gmail.com

subject.
SUMMARY
Here I am attaching a TIFF picture, which when opened using Gwenview (and
sometimes also happens when just rendering its thumbnail) will crash the
program.
STEPS TO REPRODUCE
1. Open the attachment.
OBSERVED RESULT
With a 40% chance:
```
Segmentation fault (core dumped)
```
otherwise with a 10% chance:
```
free(): invalid pointer
Aborted (core dumped)
```
otherwise the image will open and look corrupted and cropped off, but moving
will result in the following:
```
gwenview: malloc.c:4009: _int_malloc: Assertion `(unsigned long) (size) >=
(unsigned long) (nb)' failed.
Aborted (core dumped)
```
EXPECTED RESULT
No crashes and proper image (Krita works, eog displays nothing but does not
crash).
