Make the SGI Movie mime magic more specific to avoid false positives on text files starting with MOVI
<mime-type type="video/x-sgi-movie">
<magic priority="50">
- <match value="MOVI" type="string" offset="0"/>
+ <match value="MOVI\x00" type="string" offset="0"/>
+ <match value="MOVI\x01" type="string" offset="0"/>
+ <match value="MOVI\x02" type="string" offset="0"/>
+ <match value="MOVI\xfe" type="string" offset="0"/>
+ <match value="MOVI\xff" type="string" offset="0"/>
</magic>
<glob pattern="*.movie"/>
</mime-type>
