            Bug ID: 470074
           Summary: Tab title is incorrect, appears to incorrectly parse
                    /proc/$PID/stat for the name of a process
    Classification: Applications
           Product: konsole
           Version: 23.04.1
          Platform: Fedora RPMs
                OS: Linux
            Status: REPORTED
          Severity: minor
          Priority: NOR
         Component: general
          Assignee: konsole-de...@kde.org
          Reporter: clay...@claytontii.com
  Target Milestone: ---

Created attachment 159160
  --> https://bugs.kde.org/attachment.cgi?id=159160&action=edit
observed result of a incorrectly parsed executable

Run the following in a terminal window
1.  cp $(which sleep) brokentab\(title
2.  ./brokentab\(title 10000

OBSERVED RESULT
the tab title appears to incorrectly parse "(" and uses the rest of entire
result of /proc/$PID/stat after the one in the executable name 
see attachment 1

EXPECTED RESULT
tab title should show just the executable name: brokentab(title

I expect the problem to occur here:
