[Bug general/4222] New: Frysk crashes when trying to open the source window to view a stack trace

["swagiaal at redhat dot com" <sourceware-bugzilla@sourceware.org>]

Run Frysk Monitor on any program, cause the program to fork, or clone, then
double click on one of the events which has a stack trace symbole next to it.

Here is the error from trying to do this with nautilius:

java.lang.NullPointerException
   at lib.dw.DwarfDie.getDecl(FryskGui)
   at frysk.cli.hpd.SymTab.setSubprogram(FryskGui)
   at frysk.cli.hpd.SymTab.setFrames(FryskGui)
   at frysk.gui.srcwin.SourceWindow.generateProcStackTrace(FryskGui)

   at frysk.gui.srcwin.SourceWindow$LockObserver$31.run(FryskGui)
   at org.gnu.glib.CustomEvents.runEvents(libgtkjava-2.8.so)

and here is the stack trace I was trying to view:
