FYI, I'm tinkering with writing .ico files and tried to visualise the result on Linux, which gave me an error message:
%> gwenview5 test.ico QImageReader::read() using format hint "ico" failed: "Unknown error" A bad Qt image decoder moved the buffer to 22 in a call to canRead()! Rewinding. Image format is actually "ico" not "ico" This is with Qt 5.7.1 , and it happens with ico files created by QtIcoHandler itself, and with the 3rd party icotool utility. The number of icons in the file makes no difference. Is this a bug?
