The packages powdertoy once installed causes problem.

The content of a file that it installs is not valid.
The file in question is:
  /usr/share/mime/packages/powdertoy-save.xml
and the issue is due to the following extract:

        <mime-type type="application/vnd.powdertoy.save">
                <comment>Powder Toy save</comment>
                <glob pattern=*.cps/>
                <glob pattern=*.stm/>
        </mime-type>"

Note the single double quote at the end of </mime-type>
and *.cps *.stm not being surrounded by quotes

When installed this error is printed:
# /usr/share/mime/packages/powdertoy-save.xml:5: parser error : AttValue: " or ' expected
#             <glob pattern=*.cps/>
#                           ^

#             <glob pattern=*.stm/>
#                           ^
# /usr/share/mime/packages/powdertoy-save.xml:6: parser error : attributes construct error
#             <glob pattern=*.stm/>
#                           ^
# /usr/share/mime/packages/powdertoy-save.xml:6: parser error : Couldn't find end of Start Tag glob line 6
#             <glob pattern=*.stm/>
#                           ^
# Failed to parse '/usr/share/mime/packages/powdertoy-save.xml'

Such error message is repeated also later when other packages are installed.

There are two simple ways to fix the problem:

1) add a patch with a content like:
--- The-Powder-Toy-93.3/resources/powdertoy-save.xml.ori        2024-03-05 21:16:59.051478441 -0400

+               <glob pattern="*.stm"/>

 </mime-info>

or

2) add in the spec file:
 %prep
 %setup -q -n The-Powder-Toy-%{version}
+sed -i '/\/mime-type/s@"@@;/pattern=/{s@=@="@;s@/@"/@}' resources/powdertoy-save.xml

 %build

Which one to use is a matter of taste.
The problem is present in Leap 15.5 and 15.6.
The package in the games project is not affected as upstream
has already fixed the issue in the more recent version
present there.
