Here are a few steps to troubleshoot and potentially resolve this issue:

1. Check for Known Issues:
Verify if there are any known issues or bug reports related to test-json or 
test-json-instruction for libdbusmenu on Ubuntu Vivid. Sometimes, specific 
tests may have known problems that are documented.

2. Run the Test Manually:
Try running the test-json-instruction manually to see if it provides any more 
detailed output or logs that could indicate why it is hanging. You can navigate 
to the test directory and run the test directly:

cd /tmp/buildd/libdbusmenu-12.10.3+14.10.20140610/builddir/gtk2/tests
./test-json-instruction

Observe any errors or hanging behavior.

3.Increase Verbosity:
Increase the verbosity of the test execution to gather more detailed logs. This 
can often be done by setting environment variables or modifying the test 
invocation. For example, setting G_DEBUG or DBUS_VERBOSE might provide more 
insights:

export G_DEBUG=all
export DBUS_VERBOSE=1
./test-json-instruction

4.Timeout Handling:
Implement a timeout mechanism to prevent the test from hanging indefinitely. 
You can use tools like timeout in Linux to limit the execution time of the test:

timeout 300s ./test-json-instruction

This will terminate the test if it runs for more than 5 minutes.

5.Debugging Tools:
Use debugging tools like gdb to attach to the test process and see where it is 
hanging:

gdb --args ./test-json-instruction

Once inside gdb, you can run the test and interrupt it when it hangs to
inspect the call stack:

run
^C
backtrace

6. Update Dependencies:

Ensure that all dependencies for libdbusmenu are up to date. Sometimes
issues arise from outdated libraries or tools. You can update your
system packages using:

sudo apt-get update
sudo apt-get upgrade

7. Isolate the Test:
Isolate the test-json-instruction from the rest of the build process to see if 
it hangs independently. This can help determine if the issue is with the test 
itself or how it interacts with the build environment.

8. Consult Documentation and Community:
Look into the libdbusmenu documentation or reach out to the community for 
advice. The developers or other users may have encountered and resolved similar 
issues.

By following these steps, you should be able to gather more information
about why the test-json-instruction is hanging and find a suitable
resolution. If the issue persists, consider filing a bug report with
detailed logs and findings.

If none of these steps resolve the issue, you might need to gather more
