Why does PDF generation with custom logo for alerts fail?

[bohanlon_splunk]

I have set a custom image/logo for my generated alerts.

My Setup:
OS=CentOS07
Splunk=6.5.0
Architecture=Standalone instance (SH and IDXer in one box)
$SPLUNK_HOME=/opt/splunk6.5.0

My Config
./etc/system/local/alert_actions.conf
[email]
mailserver = mymailserver
pdf.header_left = logo
pdf.header_right = none
pdf.logo_path = search:myfolder/image001
pdf.html_image_rendering = 0

I have put my custom image here:
/opt/splunk6.5.0/etc/apps/search/appserver/static/myfolder/image001.png

PDF generation is broken with error of this form in $SPLUNK_HOME/var/log/splunk/pdfgen.log;
"pdfrenderer:427 - Failed to retrieve customize logo error [Errno 2] No such file or directory:"

Cause:
This appears to be a defect with the PDF generator's handling of folders.
Splunk bug reference = SPL-136094

Workaround:
When I put images here;
/opt/splunk6.5.0/etc/apps/search/appserver/static/
Result = Working fine with my image.
