A 'fake' .icc file to crash krita
SUMMARY
This happens with appimages from 4.3.0 to the Mar10 4.4.4 alpha (git c7f093c)
and the Mar10 5.0.0 prealpha (git 2bd49f3).
An invalid .icc file, 'kritacrash.icc', is attached, which is actually a text
file.
The same behaviour is observed if you deliberately corrupt a genuine .icc or
.icm file with random text insertions.
Despite the crash, the invalid file is imported.
On restart it is detected as invalid and is not included in colour profile
lists.
A further attempt to import it has no effect.
I suspect that this crash is not likely to be encountered often.
STEPS TO REPRODUCE
1. via Image -> Convert Image Colour Space -> Colour Browser, import the
kritacrash.icc file.
2. Restart after the crash.
3. Repeat Step 1.
OBSERVED RESULT
1. Crash with terminal output at the end:
kf5.kwidgetsaddons: Invalid pixmap specified.
[Note: The output line above happens as soon as the colour browser is opened.]
Lcms2 error: 11 not an ICC profile, invalid signature
Lcms2 error: 11 not an ICC profile, invalid signature
Failed to load profile from
"/home/adminahab/.local/share/krita/profiles/kritacrash.icc"
Lcms2 error: 11 not an ICC profile, invalid signature
Segmentation fault
The kritacrash.icc file is in the krita resources 'profiles' subfolder.
2. Terminal output at the start:
Lcms2 error: 11 not an ICC profile, invalid signature
Lcms2 error: 11 not an ICC profile, invalid signature
Failed to load profile from
"/home/adminahab/.local/share/krita/profiles/kritacrash.icc"
Invalid profile : "/home/adminahab/.local/share/krita/profiles/kritacrash.icc"
""
3. No visible effect.
Terminal output at the end:
kf5.kwidgetsaddons: Invalid pixmap specified.
[Note: The above output happens as soon as the colour browser is opened.]
EXPECTED RESULT
1. No crash: The invalid file should be detected as invalid and not imported.
A warning/advisory message should be displayed.
