  Well it is ... 
  Validation happens before namespace recognition.
You must use the QName in the DTD as seens in the instance:

<!DOCTYPE giml:giml SYSTEM "/opt/gitk/share/gitk/giml.dtd">
<giml:giml xmlns:giml="http://gitk.sourceforge.net/";>
    <giml:context/>
</giml:giml>

and 

<!ELEMENT giml:glim (glim:context+)>
<!ELEMENT giml:context (#PCDATA)>

and don't forgot to add xmlns:giml as part of 
<!ATTLIST giml:glim

Or use the default namespace 
   <giml xmlns="http://gitk.sourceforge.net/";>
      <context/>
   </giml>

and keep your DTD as-is

  And please make sure you use the latests versions of libxml2
