Error in Fiori Launchpad "could not start the app due..."

Question

Hello everyone,
I am having a previously unseen (well, at least for me) error which raises on a click on the tile "Track Purchase Orders" on the SAP Fiori Launchpad:
"Could not start the app due to an internal error" (see the screenshot attached)
I haven't found any help on this error on Google and SAP portals.
The other applications work fine. So did this one before the implementation of SAP_UI 740 SP09 (before that it was SAP_UI 740 SP08). We applied all the notes specified in this post http://scn.sap.com/docs/DOC-56967
Components needed for Track Purchase Orders are patched to their maximum levels (UIX01EAP 100 SP03 and SRA020 600 SP05). OData and UI5 services are activated.
Plus, this error doesn't appear in the Gateway error logs (transaction /iwfnd/error_log) so troubleshooting is difficult.
The issue is systematically reproducible and has been reproduced on several computers.
Thanks a lot if you have any insight about this issue!
Best regards,
Guillaume

Thank you for replying.
I have inspected the element and clicked on the tile. The network tab is below:
The status seems OK.
The response for ResolveLink:
{"d":{"results":[{"__metadata":{"id":"http://<server>:<port>/sap/opu/odata/UI2/INTEROP/NavTargets('PurchaseOrder-track~68')","uri":"<server>:<port>/sap/opu/odata/UI2/INTEROP/NavTargets('PurchaseOrder-track~68')","type":"INTEROP.NavTarget"},"id":"PurchaseOrder-track~68","shellType":"FLP","postParameters":"","text":"Track Purchase Order","applicationData":"SAPUI5.Component=ui.s2p.mm.purord.tracking","applicationAlias":"TrackPurchaseOrder","applicationType":"URL","url":"/sap/bc/ui5_ui5/sap/mm_purord_tpo"}]}}
I'm surprised that gbapp_poapproval and sra001 OData services are called here (with an intriguing ";mo")... We have found these errors in our /iwfnd/error_log screen after the SAP_UI 740 SP09 patch. Seeing this, we have installed GBAPP002 600 SP6 and SRA001 600 SP4 and activated the OData services but have not tried to use the corresponding apps (meaning that we have not done any other app implementation tasks because we don't really intend to for the moment).
In case the two problems are related, these are the responses to these requests:
